In modern society, a lot of people think that giving birth is either wrong if it leads to some suffering or at the very least non-morally optional. However, saving a life is considered good. Why is creating a life valued lower than saving one? Shouldn't a newly created person have more value than another person closer to death?
If everyone was destined to hypothetically go to heaven, would it not be a moral obligation to procreate as much as possible?
Even in cases where for example the fetus may have disabilities, would it not be better to be alive with disabilities than to not be alive at all? Most people with disabilities enjoy life and are grateful for existing. So why are abortions often times considered non-moral choices? At the very least, shouldn't the choice to not have an abortion be considered morally praiseworthy/supererogatory.
Shouldn't natalism and having large families be encouraged from a utilitarian perspective?
In summary, I am mainly confused and wanting to understand why modern societal philosophy seems to share this view. Are there any contemporary philosophers that give well-reasoned arguments about why existing persons take precedence over potential people?
