make no damned sense. Destroying Spira will not save it, and we see proof of that thousands of times throughout the game. Heck, Seymour is proof of it himself. He was destroyed, he died, and yet he is not at rest or at peace, instead he gets even more obsessive over his destruction goals. He's more driven, more determined, and more boring after he's dead.
Last I checked most people don't become Unsents after they die. It takes a lot of willpower and strength that I guess the average Spiran doesn't have.
