The Wolf in Sheep's Clothing response

The maxim of the story is that never trust a cunning person who acts opposite of his nature.If he is sweet talking and timid looking on the outside but hides malice and evil intentions at heart,he may when the time comes harm you, or stab you in the back.Such a person may look like a sheep,sweet,timid and benevolent.But, he has traits of a wolf in his heart,cunning,and malevolence ,hence a proverbial wolf in a sheep's clothing.
