The father has no rights regarding abortion. Once the baby is born the father has a right to fight for visitation or custody if the baby is born out of wedlock.
If the father tried to kill the fetus he would have to harm the mother, so at minimum that would be an assault on the mother. I think it varies by state whether killing the fetus is considered murder or not if done by someone other than the mother aborting.
I think without Roe v. Wade abortion would be completely illegal except probably in the case of the pregnancy threatening the life of the mother. Even then who knows how that would be carried out. A lot of people and I guess religions put the life of the fetus first, which is beyond my comprehension.
@josie You can’t be serious. Plus, even if that were the case, as long as the women you describe are choosing to abort who cares?
