What term refers to establishing a clear distinction between right and wrong?

The term that best refers to establishing a clear distinction between right and wrong is "ethics." Ethics encompasses the principles and values that guide individuals and groups in determining what actions are considered right or wrong. This concept plays a crucial role in various fields, including law enforcement, as it helps officers navigate complex situations where moral dilemmas may arise.

While "morals" also deals with concepts of right and wrong, they often refer to personal beliefs and values held by individuals, which can vary greatly from person to person. "Legality" pertains to the law and what is deemed acceptable within a legal framework, but it does not inherently address ethical considerations unless those laws align with ethical standards. "Conduct" refers to behavior but does not explicitly define the underlying principles that justify why certain actions are considered right or wrong. Thus, "ethics" is the more accurate term for discussing the frameworks that determine right from wrong in a broader sense.
