Consequentialism is an ethical theory that judges the rightness or wrongness of actions based on their outcomes or consequences. According to this view, an action is considered morally right if it leads to positive results, such as happiness or well-being, and wrong if it results in harm or suffering. One of the most well-known forms of consequentialism is utilitarianism, which focuses on maximizing overall happiness for the greatest number of people. This approach emphasizes the importance of considering the effects of actions on all individuals affected, rather than adhering to strict rules or duties.
