“Vimes felt his hand begin to move of its own accord--And stopped. Red rage froze.There was The Beast, all around him. And that's all it was. A beast. Useful, but still a beast. You could hold it on a chain, and make it dance, and juggle balls. It didn't think. It was dumb. What you were, what you were, was not The Beast.”
“Who knew what evil lurked in the hearts of men? A copper, that's who. (...)You saw how close men lived to the beast. You realized that people like Carcer were not mad. They were incredibily sane. They were simply men without a shield. They'd looked at the world and realized that all the rules didn't have to apply to them, not if they didn't want them to. They weren't fooled by all the little stories. They shook hands with the beast.”
“I could feel their grief as if it were a beast holding us down.”
“There is a savage beast in every man, and when you hand that man a sword or spear and send him forth to war, the beast stirs.”
“Garden of Pain, I need you. What were the songs of beasts to the cries of sentient souls?”
“That's some moon""Stop talking about my ass, you beast.”
