Kind of what the whole thing in civil war was. Tony was looking to absolve his guilt over the people they failed to save while looking for more and more authoritarian methods of keeping the world "safe".

Cap was much more for freedom and while the idea that the avengers should have absolutely no oversight is absurd, the question of who should be the oversight was important and much of what the avengers did could not wait on a committee to decide to act (also, the last time a committee did act they decided to nuke New York)
