Instilling fear in others gives one power. If these people fear power then one achieves even more power. If you yourself have power, but you fear power, then you will most likely give up this power or suffer from sever anxiety....
I'm more or less thinking about the second example here except if there was no possibility of giving up the power.
They become the Master... the Philosopher King. Damn, so many lines from Tao Te Ching come to mind... but let's go with this one... 17 When the Master governs, the people are hardly aware that he exists. Next best is a leader who is loved. Next, one who is feared. The worst is one who is despised. If you don't trust the people, you make them untrustworthy. The Master doesn't talk, he acts. When his work is done, the people say, "Amazing: we did it, all by ourselves!"
