I don't believe we will se immortality anytime soon. I mean, even if they manage to make your skin look younger, and clone new organs to replace defective ones, what about the brain? It will continue to age and develop more complex problems the older it gets. And even then, if immortality was invented that would raise massive sustainability issues, because of the massive population boom.
Under a capitalist / classist system? Yes, it will go full Zardoz, with floating faces saying "the gun is good, the penis is evil", and cultist running with Beach-Borat with boots - like outfits and all, but I can't see how under a communist system this can in any way become bad.
