I really don't believe that he, or any other doctor, doesn't know better than to engage in such behavior when treating patients [of any gender].  I might believe that he convinced himself he could get away with it, but I think most likely it's a compulsive behavior [due to stress, ego, who knows what] that isn't going to be 'cured' by a little education on boundaries and ethics.  A 3rd party chaperone is mandatory if this man is going to continue practice, and should not be discontinued for the duration of his practice.
