Mr. White: You can't leave this guy with them.
Nice Guy Eddie: Why not?
Mr. White: Because he's a fucking psycho. And if you think Joe's pissed off, that ain't nothing compared to how pissed off I am at him, for putting me in the same room as that bastard!
Mr. Blonde: See what I've been putting up with, Eddie? I fucking walked in here, I told these guys about staying put. Mr. White whips out his gun, he's sticking it in my face, calling me a motherfucker, saying he's gonna blow me away and blah, blah, blah, blah, blah.
Nice Guy Eddie: If you fucking beat this prick long enough, he'll tell you he started the goddamn Chicago fire, now that don't necessarily make it fucking so!
Mr. Pink: I don't wanna kill anybody. But if I gotta get out that door, and you're standing in my way, one way or the other, you're gettin' outta my way.
Mr. White: The choice between doing ten years and taking out some stupid motherfucker, ain't no choice at all. But I ain't no madman.
Mr. Blonde: Are you gonna bark all day, little doggie, or are you gonna bite?
Chosen answer: Having just been shot a second time, he was probably dying by that point. He'd done many extremely questionable things - even murdered an innocent mom - and stood by as other terrible crimes were committed in his presence. He'd grown close to Mr. White, who'd just murdered two friends and taken a bullet for Orange's sake - even as Mr. Orange was betraying him all along. So partly this was about his attachment to Mr. White, and partly a death wish stemming from his own guilt about his actions. He knew full well what would happen but told Mr. White anyway, disregarding the consequences.
