My father has NPD (narcissistic PD) and a pretty lousy temper. He manipulated me, my family and others, and many of the times when he manipulated others I was there to see it, and from that, and from him showing/teaching me manipulation and crushing/damaging others. His father did the same to him, and as he did to my father, which did to me, a good amount of punching, etc... .

I'm still waiting, which should take 1-2 weeks or more for a phone call to take some personality tests for narcissistic and anti-social PDs. Also have schizophrenia, which isn't caused from the father.
