He was a good looking kid in a emo/feminine kind of way that seems to be popular these days.
I Cant see why he would go on a shooting rampage just cos he was still a virgin , that's just stupid.
There's a lot more here that is not known about - rich parents showing no love other than giving money thinking
they can buy emotion and true affection.
I bet he was farmed out and never knew a true mother and father - this would explain a lot of the self esteem issues.
Asperger's wouldn't turn him into a cold blooded killer - his upbringing and role models surely played a part here.
RIP to his victims
