To be moral means to conform to principles or standards of right and wrong behavior, typically those endorsed by a society, culture, or an individual's own ethical beliefs. Morality involves distinguishing between what is considered proper, right, or good conduct and what is improper, wrong, or bad conduct. Essentially, being moral means acting in ways that are aligned with these accepted codes of conduct or ethical principles, which often emphasize virtues such as honesty, fairness, and respect for others.

Morality can be viewed both descriptively, as the codes of conduct a particular society or group accepts, and normatively, as universal principles that rational people would endorse for proper behavior. It guides decisions and actions to promote cooperation and harmonious living. Morality often requires individuals to sometimes put societal or collective interests above their own immediate desires.

Thus, being moral means living according to a set of values or rules that promote what is considered right and good, helping maintain social order and integrity in interpersonal relationships.
