Oh, I like that spin. Nobody is the villain in their own story. For example, Dr Doom's (or Commander EU :P) reign over Latveria seems almost too good under certain writers. It looks like it's the Fantastic Four who are the bad guys for not letting the guy to rule the world… because Doom took a shitty country and changed it into a really neat place to live.
On the other hand, they never really change that much. It's a struggle that perpetuates itself and the good guys will always be matched by a not-too-powerful villain, so that their battle will last forever. Some heroes gather together to fight similar coalitions of villains. This is honestly only "and upon each death they will rise again to fight glorious battles, feast and rejoice with their kind" from being Valhalla. That however goes into Inception territory when remembering that Avengers actually have a Valhalla on their own. :D
