Damn, twice in a row. You win again.
Alrighty, I'll play your game troll. Have you actually stopped to think about what it is I wrote, and what it is you wrote? Let's look now...
Nah, just the fact that the first thing most people say is "he probably went insane" when it's a non-Muslim, which I don't know how you can claim is the truth already.
Saying "sounds like..." or "probably..." is not claiming any truth, it's purely speculation. It's the most likely scenario without knowing more facts and looking at the statistics. Perhaps he WAS politically motivated to go shoot up a bunch of women and kids. Perhaps he thought it might end the war or something. Perhaps he's a religious nut job doing his god's work. Perhaps, like previous military shootings, he was hell bent on murderous revenge after seeing his buddies blown up and shot up for the past 10+ years. Who the fuck knows.
Either way does it make it justifiable?
Of course it doesn't. Why are you asking such stupid fucking questions?
