Serial killers are pretty fascinating if you look at their story. If he has a smidge of intellect, he wouldn't post something like that on facebook to hurt you. If he's a sociopath, his friends would all know if he hurt yu since he posted this publicly. Sociopaths avoid that at all costs.
So no, maybe he's a little bitch and stuff, but i wouldn't fear for your safety1THIS IS NOT RELEVANT ANYMORE
