“Exactly,” Sair said dryly. “It is a commonplace that more harm is done by well-intentioned fools then by the most unscrupulous villains. A wise man learns not to judge. He may set himself certain standards, but he recognizes that they are only a personal pattern to guy his own conduct and that other standards have the same validity.”

The vampire legend, he might conclude, has served conveniently for many thousand years as a conventional folk expression of unconscious feelings of aggression and guilt.
