A behavior, trait, or belief is considered deviant if it

A) inspires feelings of revulsion or disgust.
B) departs from a norm and results in a negative reaction.
C) causes harm or injury to someone.
D) violates a law.

Deviance is defined as departing from a norm, and the negative reaction of others to that departure is a key element of deviant behavior, trait, or belief. While violating a law or causing harm to someone may be considered deviant, it is not a necessary condition for deviance. Similarly, feelings of revulsion or disgust are subjective and not necessarily indicative of deviant behavior.
