I agree and disagree. But, this is not an easy case. Does the child even have the mental capabilities to even understand an abortion? Would she truly be a victimizer in the event that her unborn is aborted? I don't know. If it were MY daughter, I would not even think of allowing her to carry a child to term and risking her physical and emotional health. And, as I said, if I am wrong may God forgive me.
She could understand later that an innocent baby was murdered because she was raped. It wouldn't be her fault, but it isn't good.
Think it through.
You just don't kill an innocent child because his father is a loathesome monster.
