If you are not begging the question, then you will permit me to answer this:

“One is faced with either performing an abortion to hopefully save the life a mother, or doing nothing in which case it is likely the mother and her unborn will decease.”

“Which of these two possible courses is moral, and if they are both moral, which is preferable?”

Yes, as your example demonstrates, we all die and life can be very unpleasant.

We are in complete agreement there.
