I mean, first of all, let me say whichever superhero first came up with the idea of wearing a cape, he wasn't really onto anything good. The number of times I'm treading on that damn thing or I throw a punch and it ends up covering my whole head. It's really not practical.
Classical tragedy was the war between good and evil. We wanted evil to be defeated and good to be victorious. But the battle in modern tragedy is between good and good. And no matter which side wins, we'll still be heartbroken.
