When the psychopath/ narcissist takes you for a ride — that is, when he is victimizing people — it’s really not personal: You’re simply not enough of a person for it to be personal. In the psychopath’s eyes, you are an expedient, nothing more. When he crosses your path, the psychopath is assessing your expediency. He is asking himself, “Is there something this impending-sucker has for me? Is there something I can take from this fool that I want? Something I can take that will make me feel good?”  From the website:  Narcissists Suck

The Narcissist is addicted to power and control, without which he feels exposed to his real feelings of inferiority, inadequacy and worthlessness.
