Why many women just let their man prey on unsuspecting girls?

Many married men prey on unsuspecting or vulnerable girls. Their wives know all the man is doing but they do nothing to save the vulnerable girls. At least these women should protect the other women, all the more so when their man is preying on them.

I think these wives are every bit to blame for letting their man become a sexual predator. And when the poor girl realises that she has been taken advantage of and approaches these wives, these women are quick to blame the girl for attempting to "seduce" their man.

Just when will women learn to protect their vulnerable sisters from sex predators they are married to?

Is it okay for these wives to turn a bland eye while the man preys on vulnerable girls? What if the next victim of such a predator is the daughter of this predator himself, in the hands of another predator whose wife in turn is turning a bland eye?
