The guy was sick. Not ‘ooo…my leg’s broken’ sick, but sick nonetheless.
Evil, no, crazy, yes.
Hitler was evil, Idi Amin was evil – this guy was a psychotic loon.
He was involutarily sectioned back in 2005 and lied on his gun application about the fact. Three of his professors voiced doubt about his ability to perform and fit in, and nothing was done about it.
It’s too easy to label something you don’t understand as ‘evil’ – its a copout.
No, I’m not defending him – but to shake your head and brush it off as ‘he must have been evil, ergo we need more guns to protect ourselves’ misses the point.
