In answer to the original question:
If one considers a cell to be alive, which I do, then one would choose the first option.
Otherwise, imo it has to do with one's beliefs which should never be discussed anywhere.
Concerning abortion I'm pro choice. Accidents happen even with all the best protection available and no one should be made to suffer, especially when a baby is involved. But it is ultimately the parents' choice and I don't think abortion should be considered murder, more like killing a mouse that has made its nest in one's home.
Or something like that.
Also, I'd like to mention that abortion is not easy. It's painful and emotionally scaring, often traumatizing the woman for the rest of her life.
Of course some don't give a frak but they are just evil.
