How about when it’s viable outside the womb, which is earlier in the western world and later elsewhere (given the effort required to deal with preemies). Before this time, it’s a cellular construct. And, similarly, I see the commandment as thou shall not kill. There’s no asterisk that I’ve seen, so people are bending a commandment as they wish to have capital punishment. Various quotes in the New Testament about judging and vengeance suggest against capital punishment as well.

Women aren’t brood mares at the beck and call of others. There is no right to inflict one’s progeny on another.

And, if the unborn are so vital, then they should be protected before and after birth, possibly until they’re an adult. Don’t see anybody saying that they have to provide medical care to the mother and unborn child. Or, are others allowed to kill the child (pr permanently cripple it) just not the mother?
