" He felt crazy sometimes. Real depravity. Late at night an electric sizzle came into his blood, a tight pumped-up killing rage, and he couldn't keep it in and he couldn't let it out. He wanted to hurt things. Grab a knife and start cutting and slashing and never stop. All those years. Climbing like a son of a bitch, clawing his way up inch by fucking inch, and then it all came crashing down at once. "

― Tim O'Brien , In the Lake of the Woods
