Which term refers to a person's sense of right and wrong?

The term that best refers to a person's sense of right and wrong is "Moral Compass." This concept encompasses an individual's ability to determine what is ethical or unethical, guiding their decisions and behavior based on their own beliefs about morality. The moral compass is shaped by various factors including upbringing, culture, religion, and personal experiences, leading each person to develop their own understanding of morality.

While ethics, values, and principles are related concepts, they represent different aspects of an individual's moral framework. Ethics refers to the formal rules or guidelines provided by an external organization or society about what is considered right or wrong. Values are deeply held beliefs that influence an individual's behavior and decision-making but are more personal and subjective. Principles are fundamental truths or propositions that serve as the foundation for a system of belief or behavior, often informing one's moral compass.

Therefore, "Moral Compass" is the term that most directly captures the essence of an individual's innate sense of right and wrong.
