“Macbeth's self-justifications were feeble – and his conscience devoured him. Yes, even Iago was a little lamb, too. The imagination and spiritual strength of Shakespeare's evildoers stopped short at a dozen corpses. Ideology—that is what gives evildoing its long-sought justification and gives the evildoer the necessary steadfastness and determination. That is the social theory which helps to make his acts seem good instead of bad in his own and others' eyes, so that he won't hear reproaches and curses but will receive praise and honors. That was how the agents of the Inquisition fortified their wills: by invoking Christianity; the conquerors of foreign lands, by extolling the grandeur of their Motherland; the colonizers, by civilization; the Nazis, by race; and the Jacobins (early and late), by equality, brotherhood, and the happiness of future generations.... Without evildoers there would have been no Archipelago.”

“The more identities a man has, the more they express the person they conceal.”
