Inner strength and outward respect. These are the values that a leader holds. Unlike the sheep or wolves, they act out a higher script- one of decency, of self-sacrifice, of public honor... Of society.
And in the pretense, it becomes reality.
I still don't get it. DO you mean that the sheep who are too weak to resist temptation do so anyway because of the expectation of fidelity by the crowd? And in the pretense of being virtuous, the sheep actually become so? Or is the pretense note referring to the leaders?
