Itachi has stated that Madara has become a shell of his former self. I have speculated about this and wondered if it was because Shodaime beat him (and he simply never recovered), or is it another reason. I believe that when Madara first summoned the 9-tails, he transferred an insane amount of his chakra into the 9-tails to both create/summon and also control. Once he was defeated and the 9-tails was sent dormant (only speculation right now) Madara lost all of the chakra he put into it, which explains why he has not been able to recover. In the first few mangas after the time-skip when Naruto first saw Sasuke again, 9-tails and Sasuke had a conversation in which the Kyuubi stated something along the lines of, "Do not kill Naruto, you will regret it." I believe this is because if the Kyuubi is destroyed, the chakra will be sent back into Madara, and he would be able to dominate the Narutoverse. I am pretty tired right now and did not feel like posting links so maybe i will do that tomorrow....maybe....but probably not.
