Let me just say that both traditional Judaism, along with Christianity itself up until about two centuries ago, there wasn't the believe that early abortion was killing a person or was murder. In the Torah, if a person caused a woman to abort, the penalty was a heavy fine, not the death penalty. In Christianity, there was the concept of "quickening", namely that it was not a child per se until there was movement inside the womb.
Also, if it were to be classified as "murder", and if a woman voluntarily has a abortion, should she be put on trial for 1st degree murder, and then if convicted given the death penalty or life in prison?
As for me, I'm personally opposed to abortion but I am unwilling to tell a women with what she supposedly must do with that which is inside her.
