That was actually the least surprising of his actions, i mean still really bad and when it happened i could not believe it but after hes already tried to kill half the team letting one critical kid who was probably going to die anyway seemed right up his alley (that sounds like im condoning it, no, its just less immoral for someone with his reasoning)
I think alot of you are kind of oversimplifying him, he wasnt just a straight psychopath, he was a psychopath for sure, but he had alot of other layers
ill have to put a david naratted fic on the back burner, somewhere around 2010 lol
