I wouldn't be so quick to nix the Madanzou theories. Here's a copypasta of what I posted in the other forum: I'd just like to throw a crazy theory out there: Danzo has the Sharingan because he's actually Madara. His plan is to become the only remaining Uchiha, leader of Konoha and therefore the most powerful Shinobi and to wipe out the Jinchuuriki while he's doing it.
Think about it: Danzo ordered Itachi to kill the Uchihas. Madara helped Itachi carry it out. He became Hokage because one of Madara's underlings almost killed the former Hokage. Prior to that, he ordered Sai to kill Sasuke. He formed Akatsuki to get rid of the Jinchuuriki. Naruto destroyed Akatsuki and Sai failed to kill Sasuke, so now he devised a plan to kill both of them. Sasuke is going to attack him at the meeting. This will inevitably cause his death (well, maybe not since Kishi's in love with Sasuke, but Madara doesn't know that). He knows if he threatens Sasuke's life, Naruto would turn on him in a second. Then he can have Naruto executed as well.Furthermore, this entire situation began because Madara sent Sasuke to capture Killerbee.
It's quite a Xanatos Roulette he set up, but there's something he didn't count on: Killerbee outsmarted Sasuke and he's still alive. Now that's one more Jinchuuriki then he was expecting and if Killerbee is discovered, Sasuke may be pardoned, since other than attacking Killerbee the only thing they can really accuse him of is Grand D*****baggery. And I think they'll let that slide since he killed Itachi, Orochimaru, and Deidara. Hell, if/when Tsuande wakes up she could just make up some bull about him going undercover to kill Orochimaru.
I don't think I'm 100% correct, but if you look at their actions it definitely seems like Danzou and Madara have been cooperating to destroy the Uchiha and the Jinchuuriki. I'm just not sure why. It's possible he wants to be the world's most powerful Shinobi, since he conspired to kill Minato (who was the strongest prior to his death) and the Uchiha, the Jinchuuriki, and the ones with the Rinnengan are the three most powerful groups in the world and Madara's actions caused all of their deaths. He also indirectly caused the deaths of the Sannin (assuming Tsunade dies), but that was probably just a convenient side effect rather than an integral part of his plan.
