Why did he have to be exonerated, though? Isn't that taking the easy way out? Shit, he's been redeeming himself since The Final Night (1996)... He saved the fucking galaxy, then God recruited him as his servant... why not cut the crap already, make him come to terms with his mistake once and for all, and have him come back as a superhero who fucked up big time once causing the death of thousands and threatening even more? That's one heck of a twist for a superhero if you ask me...
It wouldn't be easy to write a book like that, that's for sure. Not everyone would accept him and that should be reflected in the comic, but it'd be a lot more interesting than bringing back the fucking 80's as if nothing had happened.
