Moses said, Thou shall not Kill ( or murder)... don't recall him specifying species.
I do know and have discussed with a couple of women over the years who have had abortions. I must say that while neither was proud or happy that they had done so, neither had any regrets at least that they were willing to share.
I do realize that many women do suffer emotionally from the decision. Women (and men) also often suffer emotionally from relationships that go bad, marriages that end in divorces or are strife with violence. Decisions made to say or not say or do or not do things for loved ones. My wife didn't have the best relationship with her mother. It wasn't a bad relationship but there never seemed to be that unconditional love that I always felt from my parents. From my POV their were always petty spats going on somewhere in the triangle of my wife, her mother and sister. I know they all loved each other but they had a difficult time showing it. When her mother suddenly became ill and soon died there were many, many regrets felt by both my wife and her sister. If anything positive came from it is that my wife and her sister have never been closer.
My point is we all make decisions and sometimes we regret those decisions. What we learn and how we move on from those decisions is what matters.
“He shall lay his hand on the head of the burnt offering, and it shall be accepted for him to make atonement for him. Then he shall kill the bull before the Lord” (Lev 1: 4–5).
Animals (species) allowed for sacrifice were oxen, sheep, goats, and pigeons.
Brush up on your Bible.
Stipulated: Abortions are a tragedy for all involved and few feel good about it
