Yes, lots of things can save lives in dramatic ways. Not going to war might help save lives, or it might not. Spending all our money on better drugs (through more research) might save lives, or it might starve us. Killing everyone, in the long run, spares all sorts of people from having to die (by simply not being born.) Even deciding to get yourself neutered will avoid death, by avoiding life. In the end, everyone dies. (Well, except for Elijah, Enoch, Moses, and Jesus -- though some/all of these are debatable.)
