We don't know his motive as of yet though. I think psychopathy and sociopathy are very outdated terms. Fact is, the vast majority of killers or even serial killers are "normal". They behave in the same way as normal people do - have friends, have family, have girlfriends, etc. What is the abnormal part is that something in their life, whether upbringing or something else, has pushed them to the point where they do the unthinkable.Deciding to "show 'them' by killing" sounds like the definition of psychopathy to me.
Very few serial killers actually have actual brain abnormalities. The majority of them are just normal and that's the scary part. I see people saying Bryan looks like a killer and such in the photos, but I think those people are connecting what he did to his appearance. The reality is that he looks bang average and there's nothing really that out of the ordinary with him. He just looks like any other guy you'd pass by on your way home. I'd certainly pay him no mind. And nothing so far in his history raises any major flags either, if we're being honest, apart from the drug issue he's had at a very early age. But other than that - he was apparently a decent student, had a normal family (from what we know so far), had friends, was bullied then he bullied. I mean these are all things almost every kids passes through at that age apart from the drug issue..
