Tobirama made the edo tensei for madara?

[Like Naruto]

Maybe that's why he created it to use madara to save the konoha we've seen how strong he was making a zombie soldier like him is a gg sir situation.

 

[HowDidIGetPrem]

his purpose for edo tensei was to revive madara at .001% power and repeatedly kill him for entertainment. he decided to scrap the jutsu only because its true purpose failed.
