is it just me or does he look like a murderer? like if I saw him out shopping, my first thought would be 'that guy's a murderer'
I say it often to my husband when we're out and see a creeper and sometimes I can just feel their creepy, dark vibe
Oh yes, WE can see it, but lets take a look at how he sees himself.
That outfit (shudder).. Who dresses like that anymore in their day to day everyday life? C'mon; he's a student and a graduate assistant. Not even full tenured long term professors dress like that ( well, at any of the universities where I've spent considerable time as both student and teaching professor.)
To me, that "look" he has going with his fashion statement, and just after completing a particularly gruesome homicide spree, says "look at me, I'm a respectable important person going about my respectable important life". I think he dressed this way very intentionally as a camouflage and *very intentionally* got himself on security cameras in multiple locations at times of day that seemed very normal for his routine respectable normal life, thinking he was so clever that he would never ever be suspected. That murderous look WE see was probably to him the look of "I'm so important and respected that I intimidate insignificant little people like you". His students and colleagues alike have spoken of this weird intimidating attitude using other descriptive words.
I also believe the thickness we see around his midsection is likely a compression wrap of some sort (multiple possibilities here including thin neoprene) that is used to prevent blood seepage from wounds sustained that morning (or less likely from wraps used preemptively for protection applied before his attack. Its much easier to conceal wraps under a loose button down shirt and loose dress slacks than the much more common and casual tshirt and sports pants. And a white shirt at that! Of COURSE he couldnt have POSSIBLY just committed a heinous flurry of murders, heavens no. And using his intimidating kind of presence, he'd be comfortably sure nobody would even think to question his very esteemed and important position in life. What a clever one.

I believe this pathetic deviant has such a huge narcissistic self image that his mirror only has room for one image: himself. He makes space for Mother only because he sees adoration reflected back to him in her eyes. Father only exists because he's useful for summoning Mother.
He can't get reflected adoration in prison and he can't intimidate anyone there either though he laughingly tried, from behind bars, when on the phone with Mother. His future looks agonizing. Yay for that.
I'm seeking info for some psychological research: how old was BK when he first saw American Psycho, the movie he named as his all-time favorite? Did he become obsessed with it then or did that come later?
