Scenario:Lelouch sacrifices himself for the good of the world using his plan The Zero Requiem Franchise: Code Geass
LELOUCH: Suzaku, you have to kill me. You must promise.
SUZAKU: You're going through with this? No matter what?
LELOUCH: As planned, the hatred of the whole world is now focused directly upon me. And now the only thing that remains is to get rid of me and finally break the cycle of hatred. The legend of Zero wasn't dead. It lives within the hearts of the Black Knights. Schneizel will serve Zero also. With this, the world will gather not for an exchange of force but for an exchange of open dialogue around one table. Mankind will be able to move forward into the future.
SUZAKU: And that...
SUZAKU: ... is the Zero Requiem. We both realized it back in Cs' world. We knew how humanity was longing for the future.
LELOUCH: Hey, Suzaku. Geass power is similar to a wish, don't you think? It's a request to someone to give you the power to achieve what you can't on your own.
SUZAKU: A wish? No.
LELOUCH: Yes. And I'm going to grant a wish called Geass to all the people everywhere. For the future of the entire world.
The only ones who should kill are those prepared to be killed. Suzaku, you're going to be a hero now. The messiah who saved the world from Emperor Lelouch vi Britannia, the enemy of the world, as Zero.
[Suzaku stabs Zero]
LELOUCH: The punishment for what you've done shall be this, then. You will live on, always wearing that mask serving as a knight for justice and truth. You will no longer live your life as Suzaku Kururugi. You shall sacrifice the ordinary pleasures of your life for the benefit of the world. For eternity...
SUZAKU: This Geass, I do solemnly accept.
[Lelouch falls down]
LELOUCH: Yes. I... I destroy the world and create it anew.
