That's what i don't get.
Usually people who are prone to dismember people, cut them up, etc. etc. -- are people who have a history of violence, being screwed in the head, visualizing murders, etc. etc.
But for someone who is joe blow, and boom -- just murdered someone. 99.99% of the time, they are so SHOCKED by what they did, they just dump the body and don't want to see it. OJ, the mafia, murders of passion, etc. The grab the body and dump it, or they throw it in the trunk, or just leave it and there and run.
Very rarely do they go from normal happy working guy one day, to sitting ina room with a knife, cutting her head off, washing their hands, taking out the guts, putting in bags, etc. etc. Someone capable of that is usually pretty f'd in the head to begin with, and people would already have seen traits of this personality in them.
Only serial murderers do shit like that.
Not true, i dont have a history and i can think of plenty of mother fuckers i could cut up while fucking laughing. I just dont do it because forensics are to good these days. That and it would seriously cut into my beerdrinking time. So ill just rely on the goold ol evolution guidline that assholes will eventually see there own end.
