Explanation:
Ethics can be defined as the study of the behaviors that guide human behavior, that is, society is developed through a set of moral behaviors that define its values and its conception of which human behaviors and attitudes are positive or negative. Ethics then emerges as the standardization of these behaviors and moral values, it is a code of conduct for positive actions by man in society in all areas of life.
In discretionary decisions, in which there is a possibility of interpretation by the legislators, ethics appears as a normative instrument for the conduct of decisions, being a guide for the legislator to decide for what will have greater ethical value and benefits for society.
