Here's a video from You Tube by the psychopathic narcissist guru Sam Vaknin. If you can get by the accent he explains how victims become narcissistic themselves.
Disclaimer: Do a google search on Sam Vaknin before becoming one of his disciples. He is an authority because his talks are somewhat auto-biographical. There are very good reasons that he was forced to stop calling himself "Dr. Sam"
BTW, Richard is the only guy there that would give you the shirt off their back!
