In general you must either pamper people or destroy them; harm them just a little and they’ll hit back; harm them seriously and they won’t be able to… - Niccolò Machiavelli

People should either be caressed or crushed. If you do them minor damage they will get their revenge; but if you cripple them there is nothing they can do. If you need to injure someone, do it in such a way that you do not have to fear their vengeance.

I say, therefore, that the arms with which a prince defends his state are either his own, or they are mercenaries, auxiliaries, or mixed. Mercenaries and auxiliaries are useless and dangerous; and if one holds his state based on these arms, he will stand neither firm nor safe; for they are disunited, ambitious and without discipline, unfaithful, valiant before friends, cowardly before enemies; they have neither the fear of God nor fidelity to men, and destruction is deferred only so long as the attack is; for in peace one is robbed by them, and in war by the enemy. The fact is, they have no other attraction or reason for keeping the field than a trifle of stipend, which is not sufficient to make them willing to die for you. They are ready enough to be your soldiers whilst you do not make war, but if war comes they take themselves off or run from the foe; which I should have little trouble to prove, for the ruin of Italy has been caused by nothing else than by resting all her hopes for many years on mercenaries, and although they formerly made some display and appeared valiant amongst themselves, yet when the foreigners came they showed what they were.

Whether this has ever happened I know not, nor whether it ever can happen. For we see, as I have said a little way back, that a city which owing to its pervading corruption has once begun to decline, if it is to recover at all, must be saved not by the excellence of the people collectively, but of some one man then living among them, on whose death it at once relapses into its former plight; as happened with Thebes, in which the virtue of Epaminondas made it possible while he lived to preserve the form of a free Government, but which fell again on his death into its old disorders; the reason being that hardly any ruler lives so long as to have time to accustom to right methods a city which has long been accustomed to wrong.
