On one hand, forcing a rapebaby on her, either his or a random person's would be punishment, there's no guarantee she would keep it, and if she did, she would either treat the child horribly or teach him or her to be like her, thus continuing her ideals.
On the other hand, crushing her womb, would mean she has no way at all to leave behind her genes, thus she has no chance of a guaranteed legacy past her death. Meaning she can only leave behind her own history. That might still be pretty nice, but to her ? Not enough
