The anthropological theory behind fun is well-documented as a means of survival preparation; young and old animals of sufficient intelligence play games in a safe environment as a means of preparing for challenges in reality.

Steve Rogers' resurrection followed by a total victory over Osborn and his thugs would make the heroes happier, it'd make the Marvel Universe safer...and in the end, it wouldn't be as fun. We didn't evolve to enjoy security...
