If your pro life, you believe that the right to life outweighs the right to bodily autonomy (not in ALL cases, but in the specific case of what a parent has to provide their child).
Consider the following scenario: Lets say your a parent with 2 working kidneys and your 8 year old son needs a kidney transplant to survive. Pretty much any parent that isn't a deadbeat would agree to give their child a kidney. However, should you as a parent be OBLIGATED to give your kidney to save the life of your 8 year old son (when everyone believes an 8 year old son is at least as valuable as a fetus, and I also think everyone would agree that giving your kidney to save a life is less of a sacrifice than to be pregnant for 9 months to save a life)? If you believe a parent must do whatever is needed to save their child's life under the pro life ethic, you would have to answer yes to that question.
I don't necessarily think think that the right to life outweighs the right to bodily autonomy, I just believe that committing an act of murder is inherently wrong and punishable.
I would argue that you can still be pro-life and believe that the parent in this scenario has the right to refuse to donate their kidney. This is because this analogy is better used in a life support argument. Pro-lifers believe that abortion is immoral because when an abortion is performed, the direct cause of death of the zygote/blastocyst/embryo/foetus is the abortion itself and not any other outside factor, since the womb is the natural habitat for the zygote/blastocyst/embryo/foetus and it does not have any underlying medical condition which has caused it to be placed in the womb as a kind of "life support".
However, in this scenario, the eight-year-old has a kidney problem that has placed him in a condition in which he needs to rely on a part of someone else's body to live. But the fundamental difference between the cause of death in his case, and an abortion, is how that life ended and who caused it to end. If you are the parent and you refuse to donate a kidney, the child will die because of the kidney problem which caused him to be placed in this situation in the first place. The death process is allowed to continue. In an abortion, the zygote/blastocyst/embryo/foetus will die because of the abortion itself, so the death process is initiated.
However, if you are the parent and you refuse to donate the kidney because you hate your child and wish them harm, then I believe you could be punishable under law for some type of murder.
