This is just brilliantExplosion, or maybe the Super Lupus he had killed him.
I think he planned it all so that they were all fairly close to the explosion. He knew they would be too worried about civilians to worry about him.
I liked this as an ending. I mean, it was actually heart-breaking. He realizes how insignificant he is as a villain, how the superheroes make the normal people "special" because of their willingness to save them. It answers about 60 years of comic book discussion right freaking there! It tells us freaking why the villain is less than the normal people who get caught up in it, why the hero is so freaking beautiful when compared to the freaking villain who can't see just how insignificant they are.
Plus, when he seems so distraught to realize that Donna isn't coming back for him, the ending, when he wishes that he could have left Wolverine with "nothing"...
I don't know. It just seemed really sad. Like, he's "us", almost. We're running out of time, we're dying, but these superheroes aren't. Hell, they'll always be young and beautiful. I can see why he went nuts at the end.
