That definition is a little narrower than the one I intended. Wikipedia's is closer to what I mean:
Wiki wrote:Homicide is the act of one human killing another.[1] A homicide requires only a volitional act by another person that results in death, and thus a homicide may result from accidental, reckless, or negligent acts even if there is no intent to cause harm.[2] Homicides can be divided into many overlapping legal categories, including murder, manslaughter, justifiable homicide, killing in war (either following the laws of war or as a war crime), euthanasia, and capital punishment, depending on the circumstances of the death.
But I think you get at the same point later on, and I agree with you that, "down through the ages historically and culturally, the circumstances around which folks deemed specific situations involving the killing of another unlawful varied considerably." Your definition bakes in the notion of "unlawful", and under that definition I think we all have to agree that most abortion is not homicide, at least not in the United States (where it is beyond lawful, it is a constitutional right).
But my point was that even if we take as a premise that a fetus is a human, and even a human
person, it doesn't follow from that fact alone that abortion is immoral or that it should be illegal. We recognize many cases in which one person may morally or legally kill another.
Any effective defense of abortion should fall into that category, at least legally. And so I find the strongest defense to be as follows: a woman has a right to control her body, and that right trumps whatever right the fetus has. Just as we can't commandeer a kidney from an unwilling donor to save another person's life, we cannot commandeer an unwilling woman's body to incubate a child.

There are really two questions, alluded two above: one is moral, the other is legal. It may be that abortion is immoral but also that it should not be illegal (e.g. immoral because babies are good so the harm outweighs the good, but should be legal because the law should recognize bodily autonomy and personal agency over local harms).
And for the latter question, "what's in it for me" is a very promising foundation. We can justify quite a lot of law on the basis that it produces outcomes that benefit everyone (or at least most people): a strong presumption of control over ones own body has positive outcomes for everyone, so defending someone else's bodily autonomy benefits you to the extent you want to use recreational drugs or experimental medical procedures.
But the god/no god question complicates things. The existence of a god (or at least certain common interpretations of that claim) collapses the question, because there's no greater good to appeal to in finding compromise positions in the law. Even if permitting abortion creates a better society, a god-based morality can make it preferable to break the law and kill abortion doctors if that prevents even a few abortions.
More generally, to your 'fractured I', is that compatible with an objective morality that is deeply contingent, so that individual actions have true moral values, but those values may differ based on personal history? It might also be the case that X is objectively moral, and yet simultaneously objectively moral for some person is to argue that X is immoral. That's a weird outcome, but it no longer seems nihilist.
