The Vindictive Narcissist''Such men are loathsome and I find it almost impossible to feel any empathy for them, though of course they never come for individual treatment so I donít actually have to try. The word I use to describe them is reptilian: they seem so cold-blooded, without any genuine feeling for other people, and their desire to inflict pain or even destroy their former spouses seems inhuman, snake-like'' .
''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
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. Many with this condition present themselves in the best light possible and are able to easily charm others to gain their trust.'' http://www.wisegeekhealth.com/what-is-a-narcissistic-sociopath.htm
