Homicide is killing of a human. It can be deliberate (in English that is “murder”). It can be accidenta. It can be suicide, or by someone authorized by statute to kill people (soliders killing enemy soldiers in war, exeuctioners working for the government, etc.). Homicide in both Jewish and American law can be justified (e.g. in self-defense or in defnese of another) and therefore lawful.
Abortion in Jewish law is perceived as homicide which may be justifiable homicide. A physician/midwife/surgeon performing an abortion in the rare situation where it is necessary to save the mother’s life, incurs no penalty – similar to how anyone who engages in justifiable homicide incurs no penalty.
The pro-choice advocatges maintain, contrary to all scientific evidence, that the baby from conception until birth is not alive and as an inanimate mass of tissue has no more legal rights than a tumor or an infected appendix or a wart.
