I don't follow your logic. Why men? Why not society? Both men and women and non binary?
If feminism was the one who solve those problems, would that be bad? why? If crime was reduced by feminist values, would that be bad? I don't quite understand what you are trying to say here.
In fact, I don't think that men or women can solve those problems on their own. You do need all society to join in and fix them. An individual can't solve them. It is a joint effort. We don't need heroes, we do need collaboration and teams.
