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 narcissistic sociopath has this type of personality along with a noticeable lack of regard for the rights of others and a tendency to regularly violate those rights. One noted difference between a narcissistic sociopath and people with narcissism alone is that the narcissist with the sociopathy reacts strongly and sometimes even violently to negative feedback. True sociopaths generally do not respond to criticism or care what others may think of them.
