madara's izanagi never made sense, what the manga said before about izanagi was that it can reverse things while its activated, it cant undo things when its not activated
thats why danzo was in a hurry to activate izanagi by doing seals before sasuke's attack hit him that one time and why he couldnt use shisui's eye to save himself from the last stab
madara's izanagi activated sometime after his death and yet it undid things that happened before it, kishi pls
anyway I would say madara is screwed since the eye is destroyed and when the time for izanagi comes there is no eye to do the izanagi
its like asking will a bomb explode if someone comes and cuts off the wires before the set time to explode
