War is hell and not to excuse it but bad things happen simply by the terrible nature of it. We see pathological behavior everywhere, in families, in corporations, on this forum, so it's in the armed forces too. And there, of course, it's not just feelings being hurt but blood being shed. I would not doubt that abuses occur. But some of this sounds like bullshit.
This part in particular:
“I didn’t rape and kill anybody, but yeah, I shot at random civilian targets sometimes, just for fun, so yeah.”
So this is being presented as a person who has the conscience to not rape but randomly shoots? Seems somewhat inconsistent. You'd think that if anything, they'd rape but not shoot. Not the other way around.
