Rogers/Fitz.
I'm not sure we have an official code on that. I'd see him punished for what he did. Not killed, but he needs to accept responsibility for what he's done and he needs to serve time for that. It wouldn't be safe to turn him loose - here or back home, knowing who he might go running to instead.
I would like to say that in an ideal world, we'd try to help him. One Two of our newest Avengers were once on the other side of the fight as well, and they're still considered part of our team. But in order for us to help him, he needs to want to change.
