Paraphrasing of the last words of the second (and last) paladin I ever played:
"You killed my wife, you son of a bitch... you killed my little boy. Five years old. Five fucking years old. My shield is broken in two. My sword is out of reach. All I have is this dagger. Not even sharp enough to pierce your hide." He shakes his head, and turns the dagger toward his stomach. "It'll do for me, though. I hereby foreswear every oath I've made to uphold righteousness. Every oath to uphold order, to defend the innocent, give charity to the poor. Everything I've ever believed in, I renounce. And after all that, if my word still has any meaning, I want to muster all that meaning now, for these four words: I will end you. You do what you will to all these people. Carry on your merry little way, massacring innocent men, women, and children who just want to live happy, peaceful lives. But as you do, in the back of your mind, remember this: I will end you. When all is said and done, when you decide to return home... when you set foot in hell... I'll be waiting. And then, if I have to use my fingernails, if I have to bite your throat open, if I have to drag you screaming into oblivion with me, you will cease to be, and the last thing you see, hear, smell, touch, and taste, will be me. I. Will. End you." And then he ran himself through with the knife.
