Destructive behaviors occur for many reasons: Family violence, congenital brain malfunctions, deep-brain injuries, biology, negative conformity either from family or peers, drug usage, and other explanations which the psychological community discusses on a regular basis. However, there are instances when these causations don’t apply.  As a result, every individual who exhibits these behaviors doesn’t necessarily have a personality disorder.  Rather, it’s a preference over socially-acceptable behaviors.
