If everyone in that universe somehow becomes immortal, then Death will become mortal, but if everybody's immortal then that means that Death would be immortal as well, but Death needs the concept of death to exist in order to keep living, therefore he'll be in a state where he is both alive and dead, which is in a way like a state of superposition in Quantum Mechanics, where a subatomic particle simultaneously exists as both a particle and a wave.
