For all of those objections that can be raised in considering the question of a woman having an abortion due to rape or incest, horrible as these things are, I would like to see those objections prefaced by “I know it is murder, but…”, and then see how it sounds.
And one more thing: in all of this, and in many other situations where moral questions are concerned, we are always so, so careful “not to judge”. The woman’s moral culpability is not at issue here. Our society has created a “safety hatch” of legal abortion, and I realize it could be incredibly tempting to take advantage of it. One discreet trip to an abortion clinic, problem solved, no one ever has to know. I realize that we as Catholics are a religious minority, and counter-cultural at that, and no one wants to come across as judgmental. Our society doesn’t like to see people being judgmental. It is absolutely true that we cannot judge souls, but if we can’t judge behavior, then there is no use even to consider moral questions. To express the sentiment as “I know it is murder, but I cannot judge” puts things into a new light altogether.
