Well if it makes everyone feel better he did end up being a closet homosexual, and the serial killer thing is quite possible , all the red flags are there. Loner, Caucasian , mentally disturbed, doesn't talk much, never fit in with any people except stoners maybe and he is a night time security guard ( position of power) to him anyway. As for what I thought, I don't really remember but I know it scared me and I was pretty young maybe 7 or 8 and I'm sure he was in his teens.
