Given the middle road between abortion and inaction, the question naturally arises: what kind of procedures are acceptable? What makes a procedure unacceptable?
The answer is relatively simple: any procedure that is designed to crush, dismember, or in any other way remove the unborn child from his mother’s body that does not leave him intact, whole, and unharmed is morally unacceptable. Another way of putting it is that any procedure that purposefully inflicts fatal or life-threatening injuries upon the fetus is morally unacceptable. The simple reason is that any procedure that is designed to inflict fatal or life-threatening injuries to the fetus purposefully kills the fetus. Thus, performing any such procedure, even with the best of intentions, is a violation of our moral duty to not purposefully kill innocent human beings (D2).
One might wonder what an acceptable procedure for saving the life of the mother would be. For most pregnancy complications, the pregnancy can be ended prematurely, when necessary, in a morally justifiable manner, by a premature delivery of the unborn child. This can be accomplished either through induced labor, or a Caesarean section. In rare, extreme cases where this is not possible (such as a tubal pregnancy), the pregnancy can be ended prematurely in a morally justifiable manner by surgically removing the organ containing the fetus (such as the fallopian tube) from the mother’s body. Neither method of ending the pregnancy early (thus saving the life of the mother) violates the moral duties discussed above (D1* or D2). Thus, these procedures are not properly termed abortions, but rather medically-necessary pregnancy-ending life-saving procedures.

Based upon this analysis, abortion is never morally justified, even in cases where there are complications in pregnancy. More specifically, performing a procedure that is purposefully designed to kill the fetus is never morally justified. In life-threatening situations, it is morally justifiable to deliver the fetus from the womb prematurely, provided that the intent of the delivery procedure is to leave the fetus intact, whole, and unharmed, with the best chance possible for his/her survival outside of the womb. In cases where the fetus cannot be delivered in such a manner (such as an ectopic pregnancy), the organ containing the fetus may be removed in order to save the life of the mother. In no case, however, is a procedure purposefully designed to kill the unborn child ever medically necessary, or morally justified
