The worst person can bring forth benefits and the best person can cause harm on occasion. It isn't so cut and dry that a bad tree only bring forth bad fruit when applying it to people. That suggests that a bad person is an absoulte thing. Also one person's truth is another person's distortion so that really throws it off. It is a kind of rock, paper, sizzors sensibility.
Perhaps a better saying is never throw the baby out with the bathwater. Perhaps the "good book' is due for another edit. Contact the elite and see if they will accomodate the request.
