I'm not justifying the guys actions, I in fact think that it was pretty fucked up, but it's pretty easy to sit back and talk shit about how evil someone is for doing something like that but on the other hand have no idea what these guys go through on a daily basis. Essentially you have to disconnect your emotions, in fact shut them off completely, when are you in combat. Otherwise it could cost you or more importantly other soldiers lives. These guys have been over there getting shot at on a daily basis, close friends getting blown to shreds by IEDs, it's war, plain and simple and unless you've been in it you have no idea what these guys go through.
Again, I'm not justifying what the guy did, but just take a look at it from a different perspective.
Stop saying " I'm not justifying " because u ARE !! When I think that people like u get to positions of power it makes me cringe...
