"If you mean ending the world, I think that's a bit of an overreaction." To say the least. He can understand just wanting it all to be over, but he doesn't want that enough to decimate the human race... or to let either Michael or Lucifer die. "And I don't think it would've helped much."

After all, a Michael broken by being 'forced' to kill Lucifer would be even worse for Raphael to have to deal with than the usual Michael.

"He'll be glad to hear it. Let's hope he doesn't just jump on the bandwagon, huh? Or the band-Winchester." Of course he can't miss the tone. He doesn't share it, though. He may dislike Dean, sort of, though the grudging respect sometimes gets in the way of that, but if Cas and Anna wanna get in on that action, then fine, it's their choice. Dean may want him dead, but he's a decent person and he won't hurt Castiel or Anna without good reason. Also, he's kind of hot. (Objectively.) It's understandable.
