Following the approach we used for “Why Are We Here?” and “What Is Consciousness?”, the question “What Is Evil?” is especially revealing because the traditions often begin with very different assumptions about what reality itself is. Some understand evil as a rebellion against God, some as a distortion of human freedom, some as ignorance or attachment, and some question whether “evil” is even a thing that exists independently.
The Universal Human Questions: What Is Evil?
Few questions are more difficult, or more disturbing, than the question of evil. Human beings have always encountered suffering, violence, cruelty, betrayal, injustice, disease, natural catastrophe, and death. We have also encountered something more difficult to explain: the deliberate infliction of suffering by one human being upon another. We know that some things feel profoundly wrong. We recognize cruelty when we see it. We instinctively distinguish between an act of kindness and an act of torture, between compassion and hatred, between justice and oppression. Yet the moment we try to explain what evil actually is, the question becomes extraordinarily complicated.
Is evil a reality that exists independently of us? Is it the absence of goodness? Is it the misuse of human freedom? Is it ignorance? Is it attachment to the illusion of a separate self? Is suffering itself evil, or is suffering an inevitable part of existence? Does evil come from human beings, from supernatural forces, from the structure of the universe, or from the way human beings misunderstand reality?
The world’s great religious and philosophical traditions offer very different answers. Yet they share a remarkable concern. Each, in its own way, attempts to explain why human beings experience a world in which goodness and suffering exist side by side, and each asks how human beings should respond.
Christianity:
Evil as Rebellion, Distortion, and Separation from God
Christianity generally begins with the conviction that evil is not part of God’s original intention for creation. The biblical creation narratives describe creation as fundamentally good. Evil therefore represents a distortion of something that was created for good.
At the center of the Christian understanding is the reality of human freedom. Human beings are capable of choosing what is good, but they are also capable of turning away from it. The biblical story of Adam and Eve presents this turning away in symbolic form. Humanity seeks autonomy from God and thereby introduces alienation into the human relationship with God, with one another, with creation, and ultimately with itself.
Christianity consequently understands evil in several interconnected ways. There is moral evil, which arises from human choices such as murder, oppression, greed, hatred, deception, and cruelty. There is also what might be called natural evil, including disease, earthquakes, floods, famine, and other forms of suffering that do not appear to result directly from human choices.
The Christian tradition has wrestled intensely with the relationship between God and evil. If God is good, loving, and all powerful, why does evil exist at all? This is the classic problem of theodicy.
Some Christians have argued that genuine freedom requires the possibility of choosing wrongly. A world containing free creatures necessarily contains the possibility of moral evil. Others have emphasized that God does not cause evil but permits it while working within history to overcome it. Still others have suggested that human beings simply cannot see the whole picture and therefore cannot know why particular suffering is permitted.
The Christian answer ultimately moves beyond explanation toward redemption. Christianity does not merely ask why evil exists. It asks what God is doing about it.
The central Christian claim is that God enters into the suffering of creation through Jesus. The cross becomes the extraordinary Christian symbol of God’s willingness to confront evil not primarily through coercive power but through suffering love. The resurrection then represents God’s ultimate rejection of death and evil.
Christianity therefore does not regard evil as an equal power opposing God. God and evil are not two competing cosmic principles. Evil is ultimately subordinate to God and will finally be defeated.
The Christian hope is not simply that individuals escape an evil world. It is that creation itself will ultimately be healed and renewed. Evil does not have the last word.
Judaism:
Evil, Human Responsibility, and the Struggle for Good
Judaism approaches the question somewhat differently. Rather than developing a single comprehensive doctrine of evil, Jewish thought has traditionally concentrated on the reality of human responsibility, covenant, justice, and the struggle between good and destructive impulses.
The Hebrew Bible contains a strikingly realistic understanding of human beings. People are capable of extraordinary goodness, but they are also capable of terrible wrongdoing. The biblical stories do not portray humanity as consistently good or consistently evil. They portray human beings as morally conflicted.
Jewish tradition speaks of the yetzer ha-tov, the inclination toward good, and the yetzer ha-ra, the inclination toward what is harmful or destructive. The latter does not necessarily mean that human beings possess an inherently demonic nature. The impulses associated with desire, ambition, sexuality, competition, and self-interest can become destructive, but they can also be directed toward constructive purposes.
This produces a particularly important Jewish insight: the existence of potentially destructive impulses does not eliminate human responsibility. Human beings remain capable of choosing.
The Book of Job takes the question of evil to an even deeper level. Job is a righteous man who suffers terribly without understanding why. His friends attempt to explain his suffering by suggesting that he must somehow deserve it. Job rejects their reasoning. The story ultimately refuses to provide a simple explanation for suffering.
This is important. Judaism does not necessarily teach that suffering is evidence of personal sin. The Book of Job challenges precisely that assumption.
Jewish thought has therefore often been more comfortable than some other traditions with acknowledging that suffering can remain mysterious. The appropriate response is not always an explanation. Sometimes it is protest, lament, compassion, and action.
This becomes especially important in the Jewish emphasis on justice. The existence of evil creates a human obligation to oppose it. The command to pursue justice means that human beings cannot simply observe suffering passively.
Jewish thought consequently tends to place great emphasis upon what human beings do in response to evil. The question is not only, “Why does evil exist?” It is also, “What are we going to do about it?”
Islam:
Evil, Human Freedom, and Submission to God
Islam teaches that God is ultimately one, sovereign, merciful, and good. Evil therefore cannot be understood as an independent power competing with God.
The Qur’an recognizes suffering, injustice, temptation, violence, and human wrongdoing as realities of earthly existence. Human beings possess genuine moral responsibility and are accountable for their choices.
Islam also emphasizes that earthly life is a test. Human beings are placed in circumstances that reveal their character and their response to God. Wealth and poverty, success and failure, suffering and prosperity can all become occasions for moral and spiritual response.
Islamic thought distinguishes between human wrongdoing and suffering that occurs through the natural conditions of existence. Human beings can commit injustice, but not everything painful that happens is necessarily punishment for wrongdoing.
The Qur’an repeatedly emphasizes God’s mercy. At the same time, divine judgment is central to Islamic understanding. Evil cannot simply disappear into history without moral accounting. Those who deliberately perpetrate injustice remain accountable before God.
Islam therefore offers a strong moral structure in which good and evil are real categories, human beings are responsible for their choices, and God ultimately establishes justice.
At the same time, Islamic theology has wrestled with the relationship between divine sovereignty and human freedom. If God is sovereign over everything, what does it mean for human beings to be responsible for their actions? Different Islamic theological traditions have answered this question in different ways.
Yet the practical Islamic response is remarkably clear. Human beings are called to resist injustice, practice compassion, care for the vulnerable, restrain destructive desires, and submit their lives to God.
Evil is therefore not simply something to understand. It is something against which the human being must struggle.
Buddhism:
Evil as Ignorance, Attachment, and the Creation of Suffering
Buddhism approaches the question of evil from a very different starting point.
Rather than beginning with a creator God and asking why such a God permits evil, Buddhism begins with the problem of suffering itself.
The Buddha’s teaching begins with the recognition that suffering, dissatisfaction, instability, and frustration are woven into ordinary human existence. The problem is not simply that bad things happen. The deeper problem is that human beings cling to a world that is inherently impermanent and expect it to provide a permanent satisfaction that it cannot provide.
The root problem is often described as ignorance. Human beings misunderstand the nature of reality. We imagine permanence where there is impermanence, independence where there is interdependence, and a permanent self where Buddhism finds no such enduring entity.
From this ignorance arise craving, attachment, aversion, jealousy, hatred, greed, and fear. These in turn produce actions that cause suffering for ourselves and others.
Buddhism therefore does not usually understand evil as a cosmic substance or independent force. What might be called evil arises from ignorance and the destructive mental states that emerge from it.
This does not make Buddhist morality less serious. On the contrary, Buddhism places enormous importance on compassion and nonviolence. Actions matter because actions have consequences. The doctrine of karma describes the way intentional actions shape future experience and reinforce patterns of character.
The Buddhist solution to evil is therefore not primarily to defeat an external enemy. It is to transform consciousness.
The person who understands reality more deeply becomes less dominated by greed, hatred, fear, and attachment. Compassion replaces hostility. Wisdom replaces ignorance. Nonviolence replaces aggression.
Buddhism thus shifts the question from “Why does evil exist?” toward “What produces suffering, and how can its causes be removed?”
Hinduism:
Evil, Ignorance, Karma, and the Problem of Separation
Hinduism contains many philosophical and religious traditions, so there is no single Hindu answer to the question of evil.
A recurring theme, however, is the distinction between ultimate reality and the limited way human beings ordinarily experience reality.
In many Hindu traditions, ignorance, or avidya, causes human beings to misunderstand their true nature. We identify ourselves with the limited ego and with the temporary circumstances of embodied existence. From this mistaken identification arise attachment, desire, fear, anger, jealousy, and other forces that produce suffering.
The doctrine of karma provides another major part of the explanation. Actions have consequences, and human beings participate in a moral universe in which actions shape future experience.
This can make the Hindu explanation of suffering appear straightforward, but Hindu traditions have also recognized the danger of interpreting suffering too simplistically. It would be a mistake to assume that every suffering person can simply be told that their suffering is the result of something they previously did. Hindu philosophical traditions have debated the complexity of karma and the relationship between individual action, circumstance, divine reality, and liberation.
The deeper Hindu response to evil is therefore connected with liberation.
The individual ordinarily experiences himself or herself as a separate ego struggling within a world of competing desires. Spiritual realization involves seeing through this limited identification and awakening to a deeper reality.
In Advaita Vedanta, for example, the deepest truth is that Atman, the true self, is not ultimately separate from Brahman, ultimate reality. From this perspective, ignorance of our deepest nature is one of the fundamental sources of human suffering.
Other Hindu traditions emphasize devotion to a personal God, righteous action, disciplined practice, or loving service.
Despite their differences, many Hindu traditions share the conviction that human beings suffer because they do not yet see reality clearly. Spiritual transformation involves learning to see more deeply and live accordingly.
Taoism:
Evil as Imbalance and Departure from the Way
Taoism approaches good and evil in a manner quite different from the Abrahamic traditions.
The Tao is not simply a divine lawgiver who establishes a list of moral commands. The Tao is the underlying Way or pattern of reality. Human flourishing occurs when life is lived in harmony with that Way.
Taoist thought is therefore less likely to describe evil as an independent substance. Instead, destructive behavior is associated with imbalance, artificiality, excess, domination, and resistance to the natural movement of life.
The Tao Te Ching repeatedly warns against excessive ambition, coercion, domination, greed, and the desire to control everything. When human beings attempt to impose their will upon reality rather than cooperate with its rhythms, disorder follows.
This is the meaning behind the famous Taoist principle of wu wei, often translated as “non-action,” although “effortless action” may convey the idea more accurately. It does not mean doing nothing. It means acting without unnecessary force, manipulation, or resistance to the natural order.
Taoism therefore offers a subtle answer to the problem of evil. Many destructive human actions arise because people become disconnected from the Way. They seek domination instead of harmony, accumulation instead of sufficiency, competition instead of balance, and control instead of participation.
The Taoist solution is not conquest but alignment.
The wise person becomes less rigid, less controlling, less attached to ego, and more capable of moving with the deeper patterns of existence.
Indigenous Traditions:
Evil, Broken Relationships, and Disruption of Harmony
It is important to recognize that there is no single “Indigenous” understanding of evil. Indigenous traditions throughout the world are extraordinarily diverse, and their concepts of the sacred, morality, spirits, community, nature, and human responsibility differ significantly.
Nevertheless, many Indigenous traditions share an understanding of human existence that places greater emphasis on relationship and interconnectedness than does much of modern Western thought.
In many Indigenous worldviews, the human being does not exist as an isolated individual standing apart from nature. Human beings belong to a larger community that includes family, ancestors, animals, land, waters, and the spiritual world.
Within such frameworks, what Western thought calls “evil” may often be understood less as an abstract metaphysical substance and more as a disruption of right relationship.
Violence, greed, betrayal, disrespect for the land, violation of communal obligations, or failure to honor relationships can create disorder that extends beyond the individual.
Healing therefore involves restoration. The goal is not merely to punish the wrongdoer but to restore relationships and recover balance.
This perspective offers an important challenge to modern individualism. If human beings are fundamentally relational creatures, then wrongdoing is not simply an individual’s private moral failure. It can damage the entire web of relationships within which life exists.
Many Indigenous traditions consequently emphasize reciprocity, responsibility, gratitude, respect, community, and careful attention to the natural world.
The question “What is evil?” may therefore become the question “What has gone out of balance, and how can right relationship be restored?”
Modern Philosophy:
Is Evil a Reality or a Human Judgment?
Modern philosophy approaches evil with considerable skepticism about traditional answers.
Some philosophers have questioned whether evil exists as an objective feature of reality at all. Perhaps the universe simply contains events that human beings experience as desirable or undesirable, and the category of “evil” is something humans construct to express moral judgments.
Other philosophers have insisted that moral judgments can be rationally defended even if there is no divine lawgiver.
Immanuel Kant treated radical evil as a problem within human moral agency. Human beings possess the capacity to recognize moral law but can nevertheless place self-interest above moral obligation.
Friedrich Nietzsche challenged conventional Christian morality and questioned the foundations upon which Western society defined good and evil. He believed that inherited moral categories needed to be examined rather than simply accepted.
Hannah Arendt, reflecting on the Holocaust and the actions of Adolf Eichmann, introduced the influential idea of the “banality of evil.” Her argument was not that evil is harmless or insignificant. Rather, extraordinarily destructive acts can sometimes be carried out not by obvious monsters but by ordinary people who surrender independent moral judgment and simply participate in systems of wrongdoing.
This observation has profound implications. Evil may not always appear as hatred. It may appear as obedience, conformity, bureaucracy, indifference, or the refusal to think.
Existentialist philosophers approached the question differently. Jean-Paul Sartre rejected the idea that human beings can simply appeal to an external essence or divine command to determine their moral choices. Human beings are radically responsible for what they choose to become.
Contemporary philosophy has increasingly examined evil through psychology, social structures, political institutions, evolutionary theory, and neuroscience. Modern thinkers ask how aggression, tribalism, dehumanization, obedience, ideology, fear, and group identity can produce extraordinary cruelty.
The modern philosophical question therefore often becomes less “Where did evil come from?” and more “How do human beings become capable of doing terrible things, and what moral principles can prevent them?”
The Deeper Comparison
When these traditions are placed beside one another, a fascinating pattern emerges.
Christianity generally sees evil as a distortion of God’s good creation and as a consequence of rebellion, sin, and the misuse of freedom. Its ultimate answer is redemption.
Judaism emphasizes human moral responsibility, the struggle between destructive and constructive impulses, justice, and the mystery of suffering. Its response is often expressed through covenant, ethical action, lament, and the pursuit of justice.
Islam understands evil within a universe governed by God, while emphasizing human responsibility, divine judgment, mercy, and the obligation to resist injustice.
Buddhism moves the question inward. Evil is closely associated with ignorance, craving, hatred, and attachment. The answer is awakening, compassion, and liberation from the causes of suffering.
Hinduism similarly emphasizes ignorance and mistaken identification, while placing these within broader doctrines of karma, dharma, and liberation. The answer is ultimately spiritual realization and transformation.
Taoism views destructive behavior largely through the lens of imbalance and disharmony. The answer is to return to the Way, reduce coercion, and live with greater simplicity and alignment.
Many Indigenous traditions understand wrongdoing through damaged relationships and disrupted harmony. The answer is restoration, reciprocity, responsibility, and renewed relationship with the human and natural worlds.
Modern philosophy is more divided. Some thinkers treat evil as an objective moral reality, while others see moral categories as human constructions. Yet much modern thought concentrates on responsibility, freedom, psychological mechanisms, social structures, and the conditions that make cruelty possible.
Is Evil Inside Us or Outside Us?
One of the most interesting differences among these traditions concerns the location of evil.
Christianity, Judaism, and Islam recognize destructive forces within human beings but also traditionally allow for realities beyond the individual, including Satan or other forms of spiritual opposition.
Buddhism and Hinduism tend to look more closely at ignorance, desire, attachment, and mistaken identification within consciousness.
Taoism looks toward disharmony between human behavior and the natural Way.
Many Indigenous traditions emphasize the disruption of relationships.
Modern psychology and philosophy often examine the interaction between individual psychology and social systems.
Yet these perspectives need not be mutually exclusive.
A human being can possess destructive impulses. A society can create institutions that reward destructive behavior. A culture can teach people to dehumanize others. A political system can turn ordinary people into participants in extraordinary cruelty. A religious tradition can interpret evil as spiritual rebellion. A philosophical tradition can interpret it as the failure of moral reasoning.
Perhaps evil is therefore not one thing.
It may occur at several levels simultaneously.
There is the evil within the individual. There is the evil created by relationships. There is institutional evil. There is ideological evil. There is violence embedded in systems. And there is the mysterious suffering that arises without any apparent moral cause.
The Mystery of Suffering
The most difficult form of the question remains the suffering of the innocent.
It is relatively easy to understand why a murderer should be condemned. It is much harder to understand the suffering of a child, a natural disaster that destroys a community, a disease that strikes an innocent person, or the death of someone whose life seemed filled with goodness.
Here the traditions begin to diverge sharply.
Christianity ultimately places such suffering within the larger story of creation, fall, redemption, and resurrection, while acknowledging that the mystery cannot be completely explained.
Judaism often permits the question itself to remain open, even allowing human beings to argue with God.
Islam places suffering within the sovereignty and wisdom of God while emphasizing that final justice belongs to God.
Buddhism asks us to understand the conditions that produce suffering rather than assume that suffering must have been deserved.
Hinduism places suffering within the larger framework of karma and rebirth, although Hindu traditions differ considerably in how they understand that relationship.
Taoism encourages acceptance of the changing conditions of existence and a return to harmony.
Indigenous traditions often emphasize the restoration of relationship and balance.
Modern philosophy may simply acknowledge that the universe does not necessarily conform to human expectations of justice.
This may be the point at which the question of evil becomes most profound. Human beings want reality to make moral sense. We want goodness to be rewarded, wrongdoing to be punished, and suffering to have a comprehensible reason. Sometimes it does. Sometimes it does not.
What Should We Do About Evil?
Perhaps the most important insight shared across these traditions is that the question of evil is ultimately practical.
If evil is understood as rebellion against God, the response is repentance and faithfulness.
If evil is understood as injustice, the response is justice.
If evil is understood as hatred and cruelty, the response is compassion.
If evil is understood as ignorance, the response is wisdom.
If evil is understood as attachment, the response is liberation.
If evil is understood as imbalance, the response is harmony.
If evil is understood as broken relationship, the response is restoration.
If evil is understood as the failure of moral responsibility, the response is courage and ethical action.
The traditions therefore disagree about the metaphysical nature of evil, but they converge surprisingly often on the kind of person human beings should become.
They call us toward compassion rather than cruelty, courage rather than cowardice, justice rather than oppression, humility rather than domination, wisdom rather than ignorance, and responsibility rather than indifference.
Evil and the Human Future
The question “What is evil?” ultimately leads to another question: what kind of world do human beings want to create?
Every generation discovers that evil is not merely a problem belonging to the past. The capacity for cruelty remains within human beings and within human institutions. Technology can magnify both our capacity for good and our capacity for destruction. Political systems can protect human dignity or suppress it. Religious beliefs can inspire compassion or be manipulated to justify violence. Economic systems can provide opportunity or produce exploitation. Scientific knowledge can heal or destroy.
The challenge is therefore not simply to define evil. It is to recognize the conditions that allow evil to flourish.
Perhaps the deepest lesson of the world’s religious and philosophical traditions is that evil does not always begin with extraordinary acts. It can begin with small failures of attention, empathy, courage, and responsibility. It can begin when another person becomes an abstraction rather than a human being. It can begin when self-interest becomes more important than justice, when fear becomes more powerful than compassion, or when obedience replaces moral judgment.
And goodness can begin in equally ordinary ways.
It can begin with seeing another person clearly. It can begin with refusing to participate in cruelty. It can begin with telling the truth. It can begin with forgiveness, generosity, courage, hospitality, justice, or simple compassion.
The question “What is evil?” therefore becomes inseparable from another question:
What kind of human being will I choose to be in a world where both goodness and evil are possible?
That may ultimately be the most important answer offered by the world’s great traditions. Evil may remain partly mysterious, but our response to it does not have to be.
We can choose what we will cultivate within ourselves.
We can choose what we will permit within our communities.
We can choose what kind of institutions we will build.
And we can choose whether, in the presence of suffering and wrongdoing, we will become spectators, participants, or agents of healing.
The mystery of evil may never be completely solved. But the human responsibility to confront it remains.
