The answer you seek is Bio-Leninism. Here's how it works:

First you find a total social misfit who has nothing going for them except his childish grudge against society. You initiate them into a position of power by having them doing something that will haunt them for the rest of their lives if it gets leaked. Obviously catch it on tape or photo. You let them power trip and have their "revenge" against society that "wronged" them.

You now have an angry tool with whom general populace have a grudge against while you pull strings behind the scenes.

The tool will obey in order to retain safety provided by the position of power you provide them with. If they wont, you throw them back to where you pick them up: in between the commoners who already want to tear him apart. You then leak their dirty laundry and watch as the tool is disposed off by the proles while the proles get sated by tiny bit of revenge against the system that oppressed them.
