I worked with a man that admitted to torturing animals (a turtle and cat is all I remember) and eventually chased his fleeing wife and children to Edmonton where he is a wanted criminal.

Quite hard to let people know how fucked up he was when he was such a smooth talker. They found out when the police dropped by to let us know why he wasn't coming into work.

I was also married to a woman with a cluster b personality disorder, that was quite a ride, but nothing like a psychopath.

Bad things happen to people all over the world but that doesn't mean we shouldn't try to find humor where we can. It would be quite a bleak life to never hear a joke because someone, somewhere was hurt once.
