I don't want to be the woman who has been raped -the guy will be flipping furious. He's already a rapist! And think of this people-she is still raped, then she will be further brutalized because the man is insanely in pain and pissed. That's a good combination.
If a woman is going to be raped anyway, just have a condom inserted and protect her from aids or something. Don't make her a murder victim jst to prove some point.
