Reminds me of my ex boyfriends cousin. He's in the military and talks about going back to Afghanistan because of the "hunting" was good. Though he always seems to be adrift like something is on his mind so I don't know. I think he's still in the military and also always carries a gun around him. I also think has conservative views but from when I met him he wasn't spitting out politics like the other veteran seems like he does.

Not sure on what to say. Maybe something deeper is involved or maybe it's just his personality... or both? Do you talk to him? Does he see a therapist? It sounds like it could be anything.
