Marian Swift : Be proud of Johnny. And be proud of yourself. You taught him to think just like you - a gun's for killin'!
Billy the Kid : And I'll tell you somethin'. You killed Pat Garrett tonight just as surely as he killed your husband Johnny. Only it wasn't by accident.
Marian Swift : What are you saying?
Billy the Kid : I'm just saying the law meant something to Johnny. Same thing it means to Pat Garrett. Exactly! Give decent people a chance to live decent lives here in Lincoln, protecting them from the hoodlums like those trail herders out there. And men like me.
Marian Swift : [Giving Pat his gun] Use it when you have to. A gun isn't just for killing when it's worn by a man like you. Or Johnny.
