I believe that abortion before the 15th week of pregnancy should be a girl’s choice, since it has a very low probability of harming the girl. After week 15, I would give the choice to the doctor.
Where then does the choice of the unborn child comes in? The fact that you even bring up the matter regarding the safety of the mother should also let you know that the primary bearer of the brunt is the child that would be killed before ever knowing a thing about the world.
Have you considered the safety of the child?
I know the sympathy doesn't make much sense to some people since the child's face and presence is yet to be seen and felt by the society but that doesn't close up the fact that someone has to end his life before it even started because two people had fun and enjoyed themselves during the process that led to the conception of the child and another is to receive the punishment for the carelessness of other people.
