If he is alive which I doubt he is he might as well. There is no point in him living considering he's over one-hundred years past his birth.
I'm expecting this tbh: Madara under the Rattata's, or Kaguya's "influence" Preta paths Hagoromo, and the Kages and ends up ridiculously OP.I think he will RinneTensei Hagoromo and he then becomes the Final Villain.
I'd be very happy, also i'd laugh in every faildara faptard face. =DIf Madara Rinne Tinsei everyone (Neji, Jiraiya, etc.) after he gets TnJ'd?
