Evil be to him who evil thinks.

This is the English version of the French Honi soit qui malypense, the motto of the Most Noble Order of the Garter, a British order of knighthood.) The secret brotherhood took an oath of loyalty and finished their meeting by declaring, "Evil be to him who evil thinks."
