Cynicism is no more mature than naïveté. You're no more mature, just more burned.

War is society's dirty work, usually done by kids cleaning up failures perpetrated by adults.

Victory in combat is like sex with a prostitute. For a moment you forget everything in the sudden physical rush, but then you have to pay your money to the woman showing you the door. You see the dirt on the walls and your sorry image in the mirror.

I mean... if you're raised as a decent human being, killing somebody is against every moral thing you've ever been taught. And so, generally, in combat it's 'krauts,' the 'gooks,' the 'yanks' - whatever you want to do to try and make it so that it's not a human being.
