In his mind -
If the woman had not been foolish and not ignored the risk, her chances of being raped would almost certainly be reduced, correct. If the woman ignores the risk, she increases the chances of getting raped, that's right. No one is blaming the victim, but you can be a foolish victim. If you aren't careful, then yes you are partly responsible for the potential outcome and it certainly becomes her problem, the other part of the responsibility of course being with the rapist.
