The Marine Corps taught me how to kill, but it didn't teach me how to deal with killing.

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.

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.

The time for debilitating fear is before and after the mission.

He thought of the jungle, already regrowing around him to cover the scars they had created. He thought of the tiger, killing to eat. Was that evil? And ants? They killed. No, the jungle wasn’t evil. It was indifferent. So, too, was the world. Evil, then, must be the negation of something man had added to the world. Ultimately, it was caring about something that made the world liable to evil. Caring. And then the caring gets torn asunder. Everybody dies, but not everybody cares.

Everything is touched by the holy when it is in the presence of death.
