Fear makes the bureaucracy more efficient, the common people more disciplined, and the ruler’s benevolence easier for people to remember, thus making the ruler safer. Machiavelli said, “It is safer to be feared than to be loved.” A ruler who does not know how to “kill to establish might” will eventually be looked down upon by the ruled. Furthermore, benevolence and tolerance are only truly cherished and praised by people when set against a backdrop of fear and severity. Therefore, a successful ruler must possess two sides: one side is the benevolence of a saint, and the other is the brutality of a lion.
