You do realize that that statistic is miniscule but exaggerated by the abortion lobby, right?
I'm sure you realize (because of the side of the argument you're taking) that the statistic of rapes that lead to pregnancy doesn't matter in the least.
Killing the child doesn't unrape the woman. It adds to her shame. Someone wrote a book based on interviewing rape victims who bore the rapist children. They love their children and the children do not cause them to remember the rape at all - except to redeem it.
The baby is not its rapist father. It does not deserve to die for its father's sins.
Shalom.
