If Death is the personification of the actual concept of Death, then I refuse to believe he's dead.

If Death however is simply another supreme, nigh-omnipotent being like God, who has simply taken on the role of "Death", then I think someone else will simply take on the mantle. After all, does the ring not grant Death level power to the wearer...?
