What kills me is that people end up saying "Well, he was in the right, he killed his parents."
Nooooooo, Tony should have been the better man, the hero, and been better than that. You don't get to act like Tony was in the right, when he is told "he was under mind control" and he goes "I don't care, I'm going to murder him."
That doesn't make a hero. It makes a better character, and it will probably lead to a better 2nd story arc for Tony, but he's definitely *not* the hero of Civil War.
In turn it makes Tonys reaction to Star Lord in Infinity War even better, now that I think about it. Keep it cool we almost got this off! Tony knew how Peter Quill felt at the moment and how it could affect the team and mission based on how he reacted to the news of his own parents a while back. ---
