Niccolo Machiavelli

"One ought to be both feared and loved, but as it is difficult for the two to go together, it is much safer to be feared than loved...For it may be said of men in general that they are ungrateful, voluble, dissemblers, anxious to avoid danger, and covetous of gain....Fear is maintained by dread of punishment which never fails...In the actions of men, and especially of princes, from which there is no appeal, the end justifies the means."
