Okay, let's go with your view. Are you consistent? Would you support the prosecution and death penalty for mothers who have an abortion in a society where abortion is banned? If not, why not? You should have no hesitation in doing so.

Science says life begins even before conception - the semen & the ovum are 'life'. The question isn't 'when does life begin?' or even 'when does human life being?', it's 'when does personhood begin?'.
Pro-life is better re-termed to 'pro-human life'. God made all kinds of life - human life, animal life, plant life. If one is truly 'pro-life', they are vegetarian and don't use any products that require the killing of animal life.
Yes, there should be a penalty for the doctor and the mother.
In your world, when does personhood begin? Why should a newborn be considered a person? What’s special about that? And if a person has Alzhemeri’s (sp), then do they lose their personhood?
