This is conventionally correct, but again equates intellect and reason with "good behavior" and emotion and passion with "bad behavior,"  truncating the deeper human experience.  Having an affair would be bad, but is the emotion prompting this desire assumed to be bad?  Could it be pointing towards a greater reality that is holy?  Perhaps the man needs to explore a staleness in his marriage and in his roles as husband and father.  How is the Holy Spirit calling him to greater service and real joy? Is his choice to resist temptation purely "rational" or is he also motivated by fear of shame if he were to give in?  Is his love for his wife and children merely rational duty or is there also a non-rational passion to "return to his first love" (as the OT prophets say)?  He will never know if he kills the inappropriate emotion and does his duty without understanding his experience.
