You have no grasp on society if you think dozens of beings all have the same thoughts and general views. Different superheros, just like regular humans, have different methods of doing things.Some like punisher kill their enemies without question, and some like spider-man do not. Some heroes like Doc samon believe Hulk can be helped, and others like Tony stark believe Hulk is a lost cause. Civil War only proved how diffferent alot of superheros are, as they wage war with each other with litte regard at times. All this anmosity and hatred could not have begun during civil war, no it was something that was building since 1961. Superheros in the Marvel U have always been divided, civil war just took that natural division and brought it to the extreme. Even after black goliath was murdered in cold blood, they still fight, and why is that, because superheros[ and people in general] have never trully been united. Not the mutant race,not even the inhumans at times, and damn sure not a bunch of super egos in tights.
