yh, but the fact he said that means his brother's eyes are his legacy, meaning izuna has leftNow we certainly know that he died, but he didn't say that he's dead. Also Madara said something like ''Hashirama, I should have taught you how to raise from dead'', so we can come up with a conclusion that Madara knows some way to revive people. Knowing that he could have revived his brother who is still alive and known as Tobi.
What did he say that would make you people believe he could revive people? And he plain out said that his brother died. You guys are just ignoring facts.
