“You're not crazy. You're not evil. But you can't stop.”

“Knowing that you're crazy doesn't make the crazy things stop happening.”

“When you're facing down multiple attackers, you always want to make the first move. It lets them know that you're ready to fight and that you're crazy enough to get the party started. One rule of thumb in fighting is that crazy can often overcome skill and numbers, because, while a trained fighter might actually enjoy going up against another trained fighter, no one really wants to wrestle with crazy. Crazy doesn't know when it's winning. And crazy doesn't know when to stop. If you can't pull off crazy, if, for instance, you're handcuffed in a small van with six armed assailants, stupid is a decent substitute for crazy.”

“Everybody looks a little crazy if you're looking close enough and if you can't look that close, then you don't really love them.”

“Insanity is knowing that what you're doing is completely idiotic, but still, somehow, you just can't stop it.”

“You're not responsible for everything, Parker. You can't control the way things end up. Stop trying.”
