“ThunderClan warriors don't kill unless they have to”

“Redtail was a brave warrior. His loyalty to ThunderClan could never be doubted. I always relied on his judgment, for it bore witness to the needs of the Clan, and was never swayed by self-interest or pride. He would have made a fine leader.”

“I don't remember Moses writing, 'Thou shalt not kill.. unless you think you have a good reason.”

“There are two things about me you should know. Don't fight me, unless you're prepared to kill me. And don't kiss me, unless you're prepared to fuck me.”

“Go and don't come back, you can take the catmint. I have no quarrel with ThunderClan; I don't want to see cats suffer, whatever you might think. Just be careful you don't end up like a bully like your kin, Tigerstar.”

“There’s more to being a warrior than killing. A true warrior — the best warrior — isn’t cruel or mean. He doesn’t claw an enemy who can’t fight back. Where’s the honor in that?”
