Ethics seeks to address questions of morality and determine what is right versus wrong. There are two main approaches: consequentialism, which assesses the morality of an act based on its consequences, and non-consequentialism, which asserts actions are right or wrong in themselves regardless of consequences. Utilitarianism is a form of consequentialism that holds an action is morally right if it produces more overall happiness than any alternative action. Later critics argued utilitarianism failed to account for the quality of pleasure and could justify harmful actions.
