I'd say this is squeezing out the gnat and swallowing the camel. You're worried that somewhere somehow stopping a fertilized egg from implanting; and thereby, beginning to develop into a fetus MIGHT be immoral? What about the people that are actually involved? The parents, the potential baby, for that matter! Life is freaking HARD, even under the best of circumstances! Simply allowing a baby to be born into this world ultimately dooms a baby to live out a hard life, experiencing all the sorrows and hardships that go along with it, a life that ultimately ends in physical death, including whatever suffering is involved in THAT. This is ridiculous to nitpick this too death. If you haven't got a consciousness involved, then you haven't got a person! And if there's no person involved, no one's being murdered. Every egg that leaves the sack is a potential human being. The Catholics don't believe in birth control at all for that reason. Why do we over think these things to freaking death? I can't help but wonder.
