Take care lest perchance you fall into the mistake of thinking to gain more by being merciful than by being just; for to pardon him too easily that has transgressed is to wrong him that transgresses not.
Abbiate cura che non v'inganniate, pensando forse meritar piú con l'esser clemente che con l'esser giusta; perché perdonando troppo a chi falla si fa ingiuria a chi non falla.
