Why childhood bullies often grow into antisocial adults
Youth who bully their peers in their younger years frequently become more violent over time and often continue to bully others in adulthood through workplace violence, verbal abuse, and even spousal abuse. (Garbarino & deLara, 2002) The reason for this is that destructive social patterns from a person's youth will carry over into adulthood unless this behavior is corrected. After documenting just such a link in their research, Nansel et al. (2001, p. 2099) report that "their earlier pattern of achieving desired goals through bullying likely inhibited the learning of more socially acceptable ways of negotiating with others." When too much time is spent in a person's youth relating to others in a destructive manner, a child never gains the necessary experience for pro-social habits to become established.
