If you were given a chance to bring complete world peace (set aside your disbelief this is possible) but it would mean you were completely erased from existence, would you accept?
And by erased from existence, I don't mean die. I mean you don't and never did exist. There would be no afterlife as you were never born. So this isn't a sacrifice that you can gain anything from. You can't make up for any past actions or misdeeds with this noble act because you'll be complete utterly gone. Think of it as your soul, your being, your essence, the energy that makes you up being used in exchange for peace. Time would be redone so it isn't like you suddenly just disappeared. This would be you never were.
For those with children, your spouse/partner/whatever met someone else and the children were still born so no cosmic upset of reality is going to happen. Your parents had another child instead of you. There would be no other repercussions to the world beyond you no longer existing. (So no paradoxes or changes the fate of the world in some way.) And no, the other child instead of you isn't you reborn. No one would miss you or be sad or hurt or anything negative. You are completely POOF!
By complete peace, I mean total peace. No fighting, no war, no hunger, no poverty, etc. Everyone would have what the need to survive and be happy. True harmony, and a world that is perfect.
