Fucking asshole doctors giving anyone who wants them anti depressants and never trying to figure out why they needed them in the first place, and then never following up to monitor whether or not these people are taking those drugs as prescribed is a pretty big part of this. I wonder what the suicide and mass shooting numbers were before the advent of these brain altering drugs. It's not that taking them doesn't make them feel better, it's that when they feel better they stop taking them and their brain chemistry is fucked and they go off the fucking rails. Modern medicine, better living through chemistry.
And it's pretty fucking obvious why a guy like him would need the cuckoo pills. He came back from Afghanistan a kicking-holes-in-the-walls PTSD rageaholic. You don't need to be Sigmund Freud to figure that one out.
