-it is sometimes wrongly referred to as psychopathy or sociopathy. These are two dinstinct kinds of antisocial personality disorder. (Dr.David T. Lykken, wikipedia)-
if we briefly explain these two kinds; psychopaths are born with temperamental differences that lead them to risk-seeking behavior and an inability to internalize social norms. On the other hand, the doctor claimed that sociopaths have relatively normal temperaments;  their personality disorder being more on effect of negative sociological factors like parent neglect, powerty, deliquent peers, extremely low or high intelligence.
To sum up, psychopathy leans towards the hereditory whereas sociopathy tends towards the environmental.
