I don't give a f*ck if Sabo is dead or alive.

If he's dead then his sole purpose of existence was to die for the sake of Luffy's character development in the first place (just like Ace).

If he's alive we will get some really big, awkward reveal leading again to more character development for Luffy and either some boring happy end with Luffy coming to terms with his quarter-life crisis or Luffy kicking Sabo's ass but thanking him afterwards since living a life for two made him stronger and all that jazz.

But since Luffy already did come to terms with Ace's and Sabo's death there is really no need for Sabo to be alive as there would be nothing gained once his arc is finished and he'd vanish in the void of oblivion just like Vivi.
