This chapter is possibly the most well-known of the work, and it is important because of the reasoning behind Machiavelli's famous idea that it is better to be feared than loved. His justification is purely pragmatic; as he notes, "Men worry less about doing an injury to one who makes himself loved than to one who makes himself feared." Fear is used as a means to ensure obedience from his subjects, and security for the prince. Above all, Machiavelli argues, a prince should not interfere with the property of their subjects or their women, and if they should try to kill someone, they should do it with a convenient justification.
