They can all be assholes. I think that's the main point of it, tbh. Though Bobby's hypocrisy bothered me the most since unlike Sam, Dean, and Castiel, no one called him out on his bullshit. It still pisses me off that he got away with telling someone that was already suicidal that it was his fucking fault that he (Bobby, that is) hadn't killed himself already and continued to suffer.

But then I've been in the position (twice even) where I was the one standing between a loved one and their suicide when I was myself emotionally unstable, so I know exactly how much that sucks and how hard it is. I might be biased as a result but I haven't forgiven Bobby yet for being such a callous, cruel, horrible small person, especially since he just got worse at the beginning of S6 with not telling Dean that Sam was back from the dead for nearly a year.

He got better after that but holy shit, he was just a terrible person for so long. I can't get past that.

But they all are terrible people at times.
