Amortalism

From Gothpoodle

Amortalists strongly believe that it is socially destructive for people to live forever, as this can result in a stagnant, ultraconservative society dominated by individuals concerned only with continuing their own lives. Amortalist activists often attempt to influence legislation to oppose (for example) state-funded health care plans that include provision for expensive or mass longevity treatments. Amortalists also include religious groups who believe secular immortality is against God’s plan or defers heavenly rewards.

A tiny radical group, the Amortality Assassins, takes this a step further, and uses murder and terrorism against those individuals or corporations whom they see as abusing or promoting longevity.
