you're still not understanding what I was attempting to clarify. you're focused on the question of "does a fetus/convict deserve to be killed?" but I'm not attempting to address that question.
we're trying to reason about the preferences of society for either acting or choosing not to act upon a pre-natal human. this question isn't limited only to terminating a fetus or gene-hacking a fetus for intelligence. any pre-natal intervention is subject to similar questions.
