I'd just feel a little better about his noble sacrifice if he wasn't being so god damn smug about screwing everyone over. I can see how that would be a really Tony gesture.

I really think he did do what he thought was right in a lot of cases (Clor aside, because really...), but he's also n record as regretting a lot of things that he did throughout.

Also, at one point, Steve punched Iron Man in the jaw basically without provocation, and Iron Man apologised to Steve. Not saying it's healthy, but he has made it a habit.
