It's hard to know exactly what angle Madara is coming from at the moment. He has taken responsibility for his role in Uchiha killings. Being that, Itachi was chosen because, supposedly, only an Uchiha could be strong enough to take out the Uchiha. Madara was the only other available Uchiha not wrapped up in the village and therefore, Coup'. Probably the only partner that Itachi could have had otherwise, Itachi would have had to act alone against the whole clan.
Tough gig.
Yet, Madara is still trying to project an image that cares about the welfare of Konoha. Something is up with Madaras account of the Kyuubi attack, unless Kishi is dropping plot holes. We can see that it runs somewhat contrary to the earlier accounts we have been given during the Manga.
I'm starting to really believe that Madara is manipulating his involvement in the story. Which direction he is trying to take Sasuke? I have no idea. Is Madara trying to get at Tsunade, the village, Danzou and his cronies?
Perhaps, it's Madara still trying to take control of Konoha by killing Tsunade and the strongest shinobi, creating a power vacuum and becoming the next Hokage? Who is to say?
