Sociopaths are often unable to control their behavior and their expressions of annoyance, irritability and threats when faced with situations not appealing to them and they often tend to resort to threats, aggression and verbal abuse.
The way sociopaths think and operate is deeply different from most of us and thus, their reasons for their violent and abnormal behaviors are vastly different from most other people. People considered sociopaths are classified as having antisocial personality disorder (APD). While you may genuinely want to help someone with APD, recognize that the best course of action involves creating clear boundaries and recommending treatment.
