Boom. I think the living tribunal is dead, but look at Steve rogers after civil war. he handed himself over for a trial. that's being a hero. taking responsiblity for your actions no matter what, and he was right. tony was a dick.
Peter rasputin went to jail (but escaped so i guess it don't count). cyclops would have stood trial if given the chance of a trial (a fair one)
i can't remember but i don't think wanda even showed remorse. does that make her a villain?
