The first time I ran into an intellectual "peer" I was around 15, I figured out a few years later that he was a sociopath. It was cool to have someone to engage with intellectually and his extreme behaviors and actions were fascinating and we had many interests in common. At the time I considered him a friend.

But sociopaths don't have friends. So, if you have a friend who you think is a sociopath, one of those two assumptions is false.
