Book 1.22

Let us now pass on to the consideration of wrongs done to others, in avenging which the law has aimed at three ends, which the prince will do well to aim at also: they are, either that it may correct him whom it punishes, or that his punishment may render other men better, or that, by bad men being put out of the way, the rest may live without fear. You will more easily correct the men themselves by a slight punishment, for he who has some part of his fortune remaining untouched will behave less recklessly; on the other hand, no one cares about respectability after he has lost it: it is a species of impunity to have nothing left for punishment to take away. It is conducive, however, to good morals in a state, that punishment should seldom be inflicted: for where there is a multitude of sinners men become familiar with sin, shame is less felt when shared with a number of fellow-criminals, and severe sentences, if frequently pronounced, lose the influence which constitutes their chief power as remedial measures. A good king establishes a good standard of morals for his kingdom and drives away vices if he is long-suffering with them, not that he should seem to encourage them, but to be very unwilling and to suffer much when he is forced to chastise them. Clemency in a sovereign even makes men ashamed to do wrong: for punishment seems far more grievous when inflicted by a merciful man.
