what if the fetus inside her is half yours (rape voids your right to being the father of the child) (and voids your right to a say if her life is in danger)

I mean i am a atheist and i understand the concept but from the point of view of Christian Muslim Jew ect its murder and should the man not have a say

IDK really maybe i am just being stupid (The idea that something is ethically wrong is going on and i cant get it out of my head)
