Charlie, Dean and others in “Unfinished Business”

Charlie

We are going to fix this. I'm not letting what happened to me happen to you.

Dean

But it's already happened.

Sam

Cain found a way to live with it.

Dean

Yeah, after centuries of murder.

Charlie

Yeah well, there's one thing you have that he didn't. You're a Winchester. I forgive you Dean.

Dean

Yeah well, I don't.

Charlie

I know, kinda your move. How's that working out for you?

Dean

I'm so sorry kiddo.

Charlie

Then prove it.
