Men ought either to be indulged or utterly destroyed, for if you merely offend them they take vengeance, but if you injure them greatly they are unable to retaliate, so that the injury done to a man ought to be such that vengeance cannot be feared.
Niccolo MachiavelliWell used are those cruelties (if it is permitted to speak well of evil) that are carried out in a single stroke, done out of necessity to protect oneself, and are not continued but are instead converted into the greatest possible benefits for the subjects. Badly used are those cruelties which. although being few at the outset, grow with the passing time instead of disappearing. Those who follow the first method can remedy their condition with God and with men; the others cannot possibly survive.
Niccolo MachiavelliTherefore, in order not to have to rob his subjects, to be able to defend himself, not to become poor and contemptible, and not to be forced to become rapacious, a prince must consider it of little importance if he incurs the name of miser, for this is one of the vices that permits him to rule.
