Lol, again with the same nonsense from when Chapter 626 came out. Hashirama killed Madara. Deal with it. Madara admitted inferiority. Deal with it. Izanagi would have been pointless and Madara was smart not be a retard and use it during the fight, and at the point where it would have been good to use it, he couldn't.
1. He couldn't even maintain his Sharingan. Lol if you think he had enough chakra to pull off Izanagi.
2. If he had done it at any point during the fight, he would have lost PS since you need both eyes for it, and he would have died a terrible death.
3. Even if he could use it, it lets him survive one strike and he's back in the same position he was at earlier. Hashirama can sense his position so Madara can't get the jump on him.
