If you die on your death bed you ascend to God tier. If you don't well... You drift infinitely through bubbles holding your memories and the memories of those who are dead and in said bubbles as well. And if you die in those bubbles, you die again. But this time for real. The only way you can die as a god tier is if your death is either Heroic or Just. Even if you kill yourself, or die in a way that could not be described as Heroic or just, you will simply come back and basically respawn. Hope you don't get tortured to death over and over again as a god tier!
