Like, Chopper's Doctor Friend said before he died, "...People die, when they are Forgotten." Yet, I still wish there was a way to save him. Everyone who loved Ace wished they could be there to save him before he got killed. Why couldn't they switch bringing people back to life from Naruto to One piece?
I agree with you, but one piece has this great point that they don't revive people so that death becomes meaningless. At least we have Sabo now so that he can comfort the Ace fans a little xD he looks pretty similar to him now
