Once again, if rape creates human life, you can make a capable argument for saying that it is a good thing - or, at least, not a bad thing. Belittling rape as an aggressive act or attempting to justify it, either in accordance with some weird cosmic justice (God works in mysterious ways) or a general moral calculus (the woman's rights may have been abrogated, but a human life has been created; the one supersedes the other), is a common strategy of those who would see that women should serve as nothing but brood mares.
Furthermore, it is uniquely interesting that men are so adamant to propose that a child is always a reward, no matter what, because such is the nature of a child. But pregnant women are continually in a state of strife and suffer in the workplace and general society as well. Pregnancy requires a significant investment of work by the woman; it is a labor that we should not expect women to take on except with their permission. It is simply misogynist to propose that her wants and needs are secondary to the burden of pregnancy, one which may be forced on her at any time, and which she alone must reap the consequences of.
