This isn't about Bucky being able to handle it. It's about the fact that he's not a criminal, he's a man who will have had unconscionable things done to him beyond his choice or control to make him dangerous, and treating him otherwise isn't going to help him remember who he is, or make him any less dangerous.

He's gonna have so many people against him on all sides who're going to want to do exactly this to him or worse, but we've got to be better than that, Tony, for his sake.
