Continuing his theme from Chapter 7, Machiavelli discusses two other ways to becoming a prince: by criminal means or when private citizens choose a ruler from their fellow citizens. Machiavelli declines to discuss the first method at length, because it speaks for itself. Agathocles was wicked, but through his great energy became a military commander in Syracuse. In order to become ruler, he called the Senate and the leading citizens together for a meeting, and then massacred them. His ability made him a prince, but such conduct cannot be called virtuous. One can get power this way, but not glory. For example, Oliverotto of Fermo became a military commander and plotted with a few leading citizens to take over the city. His uncle arranged a lavish banquet to welcome him. On a prearranged signal, Oliverotto and his soldiers killed all the guests, including his uncle, and then terrorized the city into obedience. He was only removed from power when Cesare Borgia had him murdered at Senigallia.
Cruel acts, though evil, may be justified when they are done all at once to establish a prince's power (but not repeated) and turned to the benefit of his subjects. Cruel acts are done badly when they increase over time. A conqueror should decide how many injuries he must inflict up front and do them all at once to keep his subjects from constantly resenting them. But benefits should be handed out gradually, so that people savor them. Above all, a prince should live with his subjects in such a way that no good or bad situation can force him to change his conduct.
