End do not justify the means?

A Catholic bishop in Phoenix, after a nun under his purview was excommunicated for her role at a hospital's ethics committee's decision to allow for an emergency abortion to save the life of a pregnant woman, remarked:

I am gravely concerned by the fact that an abortion was performed several months ago in a Catholic hospital in this diocese. I am further concerned by the hospital's statement that the termination of a human life was necessary to treat the mother's underlying medical condition.
An unborn child is not a disease. While medical professionals should certainly try to save a pregnant mother's life, the means by which they do it can never be by directly killing her unborn child. The end does not justify the means.

I'm curious how the bishop is able to justify HIS ends (saving an unborn child) by allowing the mother to die (the means). This bishop inserts his own interpretation that the hospital considered an unborn child as a disease, which is comical, if not pathetic. Has Arizona moved back into the early 20th century, predating civil rights, equal rights and common sense? Or maybe the Church has lowered the intellectual bar for entry into the celibate life?
