"We can and should do better. But 'doing better' doesn’t mean simply focusing on social services and systemic reforms and ignoring the need for punishment. It means using punishment intelligently, which means using it as sparingly as possible but also as much as necessary. As Machiavelli warned his fellow opponents of tyranny, a reluctance to punish comes naturally with good-heartedness, but those unable to overcome that reluctance are as unfit to rule as those who have no such reluctance to begin with."
