Why is there evil in the world?

Buddhism does not begin with a creator God whose goodness must be defended against the reality of suffering. This matters enormously for how the tradition handles the question of evil. Rather than asking why a benevolent God permits cruelty and pain, Buddhism starts somewhere else entirely: with the observation that suffering is simply a feature of conditioned existence, and that what we call "evil" arises from identifiable causes that can, in principle, be understood and addressed. The Pali Canon, the earliest surviving record of the Buddha's teachings, presents this not as pessimism but as clarity. The first of the Four Noble Truths, often translated as "life involves suffering" or dukkha, is not a counsel of despair. It is an honest diagnosis, offered precisely because diagnoses can lead to cures.

At the heart of the Buddhist account of evil are what the tradition calls the three poisons, or the three unwholesome roots: greed (lobha), hatred (dosa), and delusion (moha). These are understood as the deep wellsprings from which harmful actions flow. When a person exploits another for financial gain, when a community turns on a scapegoat, when a nation convinces itself that its enemies are less than human, Buddhism traces these back to this same trio working at different scales. Crucially, these are not forces external to us, not a devil tempting us from outside, but tendencies that arise from within conditioned minds. Delusion is perhaps the most fundamental of the three, because it is the misperception of reality, most essentially the belief in a fixed, separate self, that generates the grasping and aversion which follow. We harm others, in this view, largely because we do not see clearly.

The concept of karma adds another layer to this understanding. Karma means, in its most straightforward sense, intentional action, and the teaching holds that such actions have consequences that ripple forward through time. This is not a neat system of cosmic reward and punishment. It is more like a description of how character forms, how habits of mind and behaviour shape the kind of person we become, and how communities and cultures can accumulate patterns of harm across generations. The Buddhist tradition is careful here: karma does not explain every instance of suffering as the deserved result of past wrongdoing. The early texts explicitly reject that reading. But it does suggest that much of what we call evil is not random, and that it is entangled with long chains of cause and effect that began long before any individual arrived on the scene. This can be genuinely difficult to sit with if you are the one experiencing undeserved harm, and Buddhism does not pretend otherwise.

Mahayana Buddhism, which flourished in India and spread across East Asia, brought additional depth to this picture through its development of the bodhisattva ideal. A bodhisattva is someone who vows to remain engaged with the suffering world rather than retreating into personal liberation. This is a significant shift in emphasis. The evil and suffering of the world are not simply problems to escape but occasions for compassion. Figures like Avalokiteshvara, the bodhisattva of compassion, became central to this tradition precisely because they embody a response to suffering that is active and relational rather than detached. Thinkers within the Yogacara school went further in exploring how the mind constructs its experience, deepening the tradition's account of how delusion operates and why it is so persistent and so dangerous.

If you are sitting with this question because something genuinely terrible has happened to you or someone you love, the Buddhist answer may at first feel insufficient. It does not offer a God who will ultimately make sense of things, or a promise that the innocent will be vindicated in some final accounting. What it offers instead is a different kind of seriousness about suffering, one that refuses to look away or to explain it away. The tradition says: this is real, this matters, and it arises from causes, which means it is not simply the permanent texture of existence. That last point is where the teaching becomes quietly radical. Evil is not a mystery built into the structure of the universe by an inscrutable divine will. It is something that grows in the soil of confusion and craving. And if it has causes, then tending to those causes, in ourselves, in our relationships, in how we build our societies, is meaningful work. Buddhism places that work squarely in human hands, which is both its great demand and its quiet form of hope.
