Consequentialism: Judging Actions by Their Outcomes

Consequentialism is the family of ethical theories holding that the moral rightness of an act depends on its consequences, in contrast to duty-based and character-based ethics.

Consequentialism is a class of normative ethical theories holding that the rightness or wrongness of conduct is determined solely by its consequences. On this view, an action is morally right when it produces the best available outcome compared with the alternatives. It is the family of views most associated with the maxim that "the ends justify the means." The best-known form is utilitarianism, which judges acts by how much they maximize aggregate well-being — classically, the greatest pleasure and least suffering across everyone affected. Other variants include ethical egoism (rightness measured by consequences for the agent), rule consequentialism (acts judged by whether they follow rules that generally produce good outcomes, rather than evaluating each act in isolation), and state consequentialism, which assesses worth by contribution to collective welfare and traces to ancient Chinese Mohism. Consequentialism is usually contrasted with two rival approaches. Deontological ethics grounds morality in duties and rules that hold regardless of outcome — some acts are simply forbidden even if they would produce good results. Virtue ethics shifts focus from the act to the agent's character, asking what a virtuous person would do. Common objections include the predictability problem (real consequences are hard to foresee, and unintended ripple effects complicate any after-the-fact judgment), the demandingness or alienation objection (Bernard Williams argued the theory can require agents to sacrifice their own commitments and projects for the sake of optimal outcomes), and the responsibility critique (G. E. M. Anscombe argued agents cannot escape moral responsibility merely by claiming they could not foresee a bad outcome). A recurring practical worry is that pure outcome-focus can endorse rewarding bad behavior whenever it happens to turn out well — collapsing intent and process into luck.
