The sad thing is that most people either have no idea or are confused how Edo Tensei works ... if Izuna was to be revived with it, it would be with both his eyes ... not eyeless.
Sasori died as a piece of flesh in a wooden puppet, yet got revived as a human.
Nagato died crippled with rods through his body, revived as normal ... the reason for he couldn't use his legs well had nothing to do with them being burned YEEEEARS ago, they already healed.
He just wasn't using his legs for like 20 years so his brain has lost contact with them.
So the excuse: "Kabuto didn't revive Izuna cause a blind Uchiha is pointless" is invalid.
