Both are learned.
Sociologists see many similarities between deviant and nondeviant behavior.
First, both types of behavior are learned. Sociologists take into consideration the norms and values to which an individual has been socialized, assume that the vast majority of individuals engaged in deviant behavior are not sick or abnormal. Often they are conforming to the deviant norms or some subculture to which they have been socialized. Deviant behavior may also be a normal response to frustrations, tensions, and stresses generated by pressures and conflicts within the structure of society and social life itself.
