Yes, that exactly! I think one of the bravest scenes I have ever seen him in was in "Sympathy for the devil" when he stepped up to Bobby (doesn't matter it was possessed Bobby since Sam didn't know) and took FULL responsibility for letting Lucifer out, not once thinking about how he was forced to do that from the outside. That one really broke my heart and still he went on, he came back to Dean and Bobby to fight with them and to make it right. This strength, this need to do the right thing and stand up for it is what I admire most about him, he doesn't care about what other people might think about him as long as he does the right thing. I couldn't do that.
