"Voldemort himself created his worst enemy, just as tyrants everywhere do! Have you any idea how much tyrants fear the people they oppress? All of them realise that, one day, amongst their many victims, there is sure to be one that rises against them and strikes back!"
"That which Voldemort does not value, he takes no trouble to understand. Of house-elves and children's tales, of love, loyalty, and innocence, Voldemort knows and understands nothing. Nothing. That they all have a power beyond his own, a power beyond the reach of any magic, is a truth he has never grasped."
