For those of us who believe that God is the arbiter of right and wrong and that the Church correctly interprets his word, a great deal of the difficulty has been removed.
And to a humanist like myself, that means a great deal of moral responsibility has also been removed. Self is not necessarily the final arbiter in a moral decision - there must be consideration for the needs of others who are affected by your choice. Beings who are capable of suffering are entitled to be spared unnecessary suffering. Scientific research indicates that a foetus (not a euphemism, but a scientifically correct and accurate term) is incapable of processing pain during the first trimester, when the vast majority of abortions are performed. Late-term abortions, which are more likely to cause pain to the foetus, are, like cases resulting from rape, comparatively very rare, and usually performed for very pressing reasons, often to do with the health of the mother.
On the other hand, the woman in whose body the foetus resides is very capable of suffering. She is also entitled to see the foetus as part of her body, since it is incapable of idependent survival before about 24 weeks’ gestation. Natural law in fact favours the survival of the mother over the foetus - this is why miscarriages (spontaneous abortions) occur, both in humans and other animals.
It is not a matter of shutting off our minds and simply doing as we are told as we still have to apply the moral teachings of the Church, but she supplies the rules which, if we correctly apply them, will lead us to the moral choice. Regarding abortion the rule is simple: it is always wrong regardless of circumstances.

The rule is never that simple, unless you are content to just be told what to do. Everything is connected. Those of you who bluster about the “millions” of abortions performed every year in the United States alone - have you stopped to think of the impact it would have on the planet had all those babies been born? Especially if they were to grow up to expect the kind of relative affluence many Americans take for granted? Humanist morality is never a matter of just making self the highest good. Other people, and other creatures, and the world in general, matter, and all are affected in one way or another by the issue of abortion. That’s what makes it complex.
As this thread seems to have grown far beyond the initial poster’s query, I’ll try to rein it in with a closing comment, as this will be my final contribution (I think I’ve made my perspective clear enough to those who care to consider it). My personal feeling is that it does no good to debate the relative moral reprehensibility of war and abortion. As I’ve commented before, both are complex issues, and both have the ability to be the source of suffering. Every instance of war or of abortion must be considered as a separate issue, for circumstances are always different. Reasons must be weighed, and the decision made on the basis of whether the harm caused is worth the overall outcome. If you want a general persective, here it is - I would consider that the impact of war on a community and the level of immediate, intense suffering caused by it are of a degree far greater than that caused by hygenic, legally available abortions, performed under the care of doctors and counsellors. From a humanist perspective, that would tend to make war the greater evil.
