The vast majority of sociopaths are very upstandin

The vast majority of sociopaths are very upstanding and respectable people on the surface. They typically present themselves as a good person, sometimes like church going family men, to others because it allows them to get away with the fucked up head games they put on people behind closed doors. By the way, that's interesting that you admit to knowing him offline. Sounds like a perfect opportunity for collusion to me.
