Dean, you're always my responsibility. [He has a temper, he's always had a temper. But even if this hadn't happened Dean would still be his priority] Everything I do, everything I did - it's because I want to protect you. You and your brother -- you're all I have. [And he's struggles now, what is the purpose of his living, after everything? It has to be to look after Dean and Sam, right?] I only want you to be safe.

[And he didn't think Dean would actually choose the freak over his own family. It hurts to realize how little he means now.]

I'll call a truce. I still have my eye on him and if he hurts anyone, you know what I'll have to do. But the past can stay there. [Because saving Dean from hell is worth a town. Heck to John it's worth a country.]
