Krampus ate my d20s
Felon said:He makes a little nick, like a shaving cut. The amount of time he spends talking to them is varied, but it's generally apparent (to me anyway) that he's not being sadistic but rather is trying to understand what makes people like them--and him--tick.
He also dismembers them while they are alive. That is why there is so much plastic, he is not neat, he just cleans up well. If he didn't want to torture them, he would off them while they were nice and unconscious. Nope, Dexter is not just an executioner, he is a torturer as well.
He is also human, which means he is not infallible. I don't think a sociopath is the best person to decide what the burden of evidence is. The hunt for evidence is part of his ritual for now, but he is not above planting evidence to save his hide. What if he misinterprets evidence and kills an innocent man? I think it would make an interesting plot arc.
