Ethics refers to well-founded standards of right and wrong that prescribe what humans ought to do, usually in terms of rights, obligations, benefits to society, fairness, or specific virtues. It is a branch of philosophy that is concerned with human conduct, more specifically the behavior of individuals in society. Ethics examines the rational justification for our moral judgments; it studies what is morally right or wrong, just or unjust. Ethics is a system of moral principles that includes ideas about right and wrong, and how people should (or should not) behave in general and specific cases. It is a set of rules that govern behavior based on principles of right and wrong. Ethics is also the process of questioning, discovering, and defending our values, principles, and purpose. It involves making decisions about how people should live their lives based on what is considered to be right or wrong. Without ethical standards, there would be no concept of right and wrong, leaving individuals to make decisions based solely on their own subjective preferences.
