I can't say what he was thinking, I leave it to the experts. PTSD effects different people differently, it's not like there are rules that say, "well you've experienced X,Y, and Z therefore your PTSD is a level such and such" many factors are involved; propensity towards violence, childhood, physical fitness, fatigue, cigarette smoker, etc., are just some I've heard about in our PTSD death by power point briefings.
Leave it to the experts, they study this stuff, that's why they have letters behind their names.
This is why we have trials, so all the evidence can be laid out before the judge and jury an they can make the appropriate determination. If he is faking it, I'm sure a decent hard working prosecutor can demonstrate that. There are consequences for a nation at war, the mental health of war veterans is one of them. Not all war fighters are model citizens, if we were we'd be cops.
