I don't consider that murder. An unborn infant, by law in most states, is
not considered a person with a right to life that supersedes the mother's right to control her own body.
A cell found on Mars could be considered life. But we don't give rights to it. While people have a right to live they do not have rights to use your body without your consent. If you do not legally give consent to being pregnant then you by law you can get an abortion. It's a constitutional right.
Even medically and empirically it's not seen as murder. I cannot see anyone rationally arguing with empirical evidence published & posted in the The National Library of Medicine (NLM).

What about rape victims? Would you force a 12 year old girl who was raped & impregnated by her drunk father or another relative to carry and go through child birth? Imagine the mental and emotional abuse you'd be putting them through.
