If a fellow is wicked,nasty and crooked by nature, no show of favours, respects and no sort of extending hospitality and godwill are likely to put a check on his behaviur filled with ill-will,hastility and rebellion.. See, a crow will reamin just a crow and surely will not turn into a royal swan even it is given repeated ceremonial baths or ablutions with ltres and literes of milk.
