Ethics deals with standards of right and wrong that guide behavior and decision making. There are three domains of human action: codified law which is enforceable, free choice where law has no say, and ethics which has no laws but standards of conduct. An ethical dilemma arises when alternative choices both have harmful consequences, making right and wrong unclear. Approaches to ethics include utilitarianism which seeks the greatest good, individualism which focuses on self-interest, and moral rights which protects fundamental human rights. Guiding ethical decisions requires considering justice, fairness, and people's basic rights.
