Not blaming, but the main reason behind his actions. I was in Iraq during the same time, and that 15 months felt like a lifetime. There's somewhat of a saying that, a soldier may leave war, but war never leaves the soldier. In all accounts, that's 100% true. For some, it wasn't and isn't easy to just "turn it off" once you return to the world. By saying this, I'm not excusing any of his actions, but I know where he's coming from.
