Watched it. Fucking dude truly was creepy and evil. Its a shame his childhood was so bad.
The dr that interviewed the ice man, put personalities like his perfectly. Guys like this and the ice man are born with this type personality. And their childhood guides how they apply that personality to their lives. Some children with this no remorse personality grow up to be hero cops, super military specialists and fearless fire fighters. The ones that get beaten and raped and unloved/unguided end up using their personality and talents for bad. Thats unreal to think about. I truly agree with this. Parents, kiss and hug your kids. Especially the weird ones.
