The charming, social climbing, unreproachable Mr. Elliot from Jane Austen's Persuasion:
Mr. Elliot is a man without heart or conscience; a designing, wary, cold-blooded being, who thinks only of himself; who, for his own interest or ease, would be guilty of any cruelty, or any treachery, that could be perpetrated without risk of his general character. He has no feeling for others. Those whom he has been the chief cause of leading into ruin, he can neglect and desert without the smallest compunction. He is totally beyond the reach of any sentiment of justice or compassion. Oh! he is black at heart, hollow and black.
