...sometimes I wonder about the people who find it unintuitive to consider that "Killing X, once X is alive and asking not to be killed" and "Preferring that X not be born, if we have that option in advance" could have widely different utility to me. The converse perspective implies that we should either (1) be spawning as many babies as possible, as fast as possible, or (2) anyone who disagrees with 1 should go on a murder spree, or at best consider such murder sprees ethically unimportant. After all, not spawning babies as fast as possible is as bad as murdering that many existent adults, apparently.
