Moral Duty Moral duty refers to the obligation to act or refrain from acting according to moral principles. Moral duties establish the minimal standards of ethical conduct. Thus, the failure to perform a moral duty properly evokes the moral judgment that the conduct is wrong, unethical or improper. There are both affirmative and negative dimensions to moral duties. Moral Virtue Moral virtue goes beyond moral duty.
Moral virtues are aspirational rather than mandatory.
Values Values are core beliefs or desires that guide or motivate attitudes and actions. They also define the things we value and prize the most, and, therefore, provide the basis for ranking the things we want in a way that elevates some values over others. Thus, our values determine how we will behave in certain situations. Ethics is concerned with how a moral person should behave, whereas values simply concern the various beliefs and attitudes that determine how a person actually behaves. Some values concern ethics when they pertain to beliefs as to what is right and wrong.
