A narcissistic sociopath is someone with a combination of narcissistic personality disorder and definitive behavioral signs of sociopathy. People with narcissism are characterized by their excessive and persistent need for others’ admiration and positive reinforcement. They generally have grandiose opinions of themselves and believe they are superior to other people. Narcissists are also frequently convinced that they are above the normal responsibilities and obligations of everyday life, so they usually have significant difficulties maintaining employment or relationships as a result. 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. A narcissistic sociopath is unable to tolerate criticism and needs constant praise, as well as deference from other people.
