Yes! If we can dismiss any obligation to a revealed standard of ethics, we feell we can also dismiss any consequences that standard may impose.
In this one life that we know we have I think we must include and consider all the possible effects to currently living people with lives to lead perhaps before those of a potential life.
A husband whose wife had been raped would presumably simply have to stand by while the rapist's child developed in his wife probably destroying their relationship. The already wronged woman not only would have the lasting reminder of rape but perhaps to a greater or lesser extent lose her chosen potential father of her children.
What of the potential life that could have been created by this couple but which now cannot be, does that count for nothing?
For me there are so many other reasons too why at least some abortions are not wrong and where dogmatic beliefs are simply not good enough, but I don't want to drone on here.
