 We generally don't give enough credit for superhero comics when it comes to narrative techniques, subtext or irony. This collection of Iron Man carries the weight of the Civil War story arc in meager four issues and provides an ending that is tragic and totally worth it. For the sake of characters and the way they have changed during implementation of Superhero Registration Act, It wasn't worth it. 
 When Iron Man and Captain America talk (and even punch) it out as themselves and their alter egos, it is difficult to take a side. In any profession there will always be some bad apples. To overcome this, laws are put in place. The government ensures these laws are followed. Isn't that a good thing? This is Tony's argument. He isn't wrong. Yes, an oversight committee is required. 
 But we aren't dealing with ordinary humans. These are people with powers. One bad apple has the capacity to bring the entire city to its knees. Both "heroes" and "villains" would come under government purview and fight along the same side, blurring the moral boundaries between the two. It is stupid to assume the identities of these people will be secret. No, they aren't similar like cops or other law enforcement officers as they aren't paid to do what they do. They chose to stay when they could have walked away from injustice. Captain America has fought in war and been part of a government that did pretty much this. Allusions of history are many. 
 These conflicts rarely get answered. They turn into something else: violence, tragedy and an aftermath that is too horrifying to clean up. You end up with a new bunch of decisions and a reality that you never calculated for. 
 I just feel sad for Tony.
