After reading 622, we can clearly see that... Madara is not an evil brat. He has the same desire to end the war as Hashirama. So what could have changed him so much?
As Tobirama stated, Madara loved his brother Izuna... may be even more than Itachi did Sasuke. So this in my mind rules out the Tobi's story of Madara. I don't think he took his brothers eyes while he was still alive, he probably got them from his corpse.(Just like how Sasuke got his EMS)
How did Izuna die? Hashirama killed him. I can't predict how it would happen but in chapter 621 page 11
Hashi: Do you want to destroy all we have done so far? All our efforts?
It is an insult to our brothers and comrades.
Madara: How dare you...
That in my opinion proves... Hashirama did kill Izuna. Also In the previous story we were told that Madara and Hasi were fighting for the title of Hokage. Really? This doesn't look like competition fight but rather a fight for revenge(fight to the death). It would be silly if they would die for the title... besides they both look like the type who wouldn't really care for the title as long as there is peace.
If this is the case for Izuna's death, then I have one small theory. After Hashi tells the story and convinces Sasuke, they would all head out to battlefield and confront Madara and Juubi. Madara will see Sasuke who looks almost the same as Izuna...I know all uchihas look alike but Sasuke and Izuna looks almost like a twin. He will have mixed feelings to whether to end the world. Seeing Sasuke might save him from Uchiha's evil.
