The level of the violence of the rape, or if rape occured at all is not a related issue to the decision to carry out an abortion. In my opinion anyway. I realize that in the case of rape, one will not be able to separate the emotions, but from a pure debate prespective, they are unrelated issues. You don't treat cancer different ways depending on how you got it. I'm of course not comparing a fetus to cancer either, it is just the best comparision I could think of.
