Assuming perfection in the methods, ending N lives and replacing them with N+1 equally happy lives doesn’t bother me. Death isn’t positive or negative except in as much as it removes the chance of future joy/suffering by the one killed and saddens those left behind.
With physical humans you won’t have perfect methods and any attempt to apply this will end in tragedy. But with AIs (emulated brains or fully artificial) it might well apply.
