Here are some other thoughts to consider:
Morally, it is WRONG for the women to abort her baby; especially since the the creator of this thread silenced the argument by saying "baby is sentient."
What happens is that people put situations (problems with going the other road) to sway us from what is really right and wrong. Morally, if the women aborted, she would be wrong. That simple, but that doesn't mean she won't be able to live with her self. "So you are saying murder is always wrong?" Yes, thus why we have the words murder and kill. If you are the reason someone dies, you have to look at if from the situation behind why. Accident/unintentional or purpose? The baby cannot be held accountable for the mother's death. We think it's the baby's fault (although unintentional), but you could argue it's the women's fault as well. If the women gets it aborted, looking from what the creator already assumed about what would happen if the baby survived, it seems like the women's motives were selfish.
Topic war: what if the situation was during a war scenario? We need the women alive to win the war or thousands/millions of people will die.
You can argue all you wan to justify killing the baby in that case, but the baby did not "ok." Morally, it's still wrong, although the women would still probably be able to live with herself. Like a judge ruling in the case of "les Miserables." Sorry poor man, what you did was WRONG=punishment. Now, the judge knows he did it to save his life (read the story if unfamiliar with this), but the if the judge rules by what is wrong and right, the poor man's excuses mean nothing.
Final thoughts: mass effect 2: the man trapped in that building who's mind was like a super computer and people basically imprisoned him because they needed his mind for the war effort (communicate with the geth). Again, we get swayed with scenarios from what is right and wrong. What they did was wrong.
So, if abortion correct to save the mother, even if the death of the mother brought ruins to so much? yes
