Dr. Mabuse is a character in a film named The Testament of Dr. Mabuse in 1933 said this,
“Humanity’s soul must be shaken to its very depths, frightened by unfathomable and seemingly senseless crimes. Crimes that benefit no one, whose only objective is to inspire fear and terror.” Because the ultimate purpose of crime is to establish the endless empire of crime. A state of complete insecurity and anarchy, founded on the destruction of the ideals of a world doomed to annihilation. When humanity, subjugated by the terror of crime, has been driven insane by fear and horror, and when chaos has become supreme law, then the time will have come for the empire of crime.
& the Joker of The Dark Knight film in 2008 said this,
Don’t talk like one of them. You’re not! Even if you’d like to be. To them, you’re just a freak, like me! They need you right now, but when they don’t, they’ll cast you out, like a leper! You see, their morals, their code, it’s a bad joke. Dropped at the first sign of trouble. They’re only as good as the world allows them to be. I’ll show you. When the chips are down, these… these civilized people, they’ll eat each other. See, I’m not a monster. I’m just ahead of the curve.
I do not know if Nolan built the joker where Dr. Mabuse was left off but he certainly is a few steps ahead than the doctor. Both are criminal masterminds of the highest degree and both are well aware of the mask our society consistently wears in order to save itself from being doomed. Both disregard this social mask of ours and strive to found a society that does not hide our basic instincts, including crime. Both are countered by the men that are not self righteous but have their feet firmly placed on the very ground of their respective societies. Plus crime is such a self-defeating way to live that it cannot last long. Crimes against crimes take place and the original crime that has no benefit to any goes down the drain. Even a society of criminals would then need a set of rules. And ironically, it will itself deny any rule/law whatsoever. From here, it certainly becomes interesting to see what these characters attempt, though only in an unreal world.
May be only upon realizing this, the Jokes wishes not to do everything himself but consistently tries to trigger the innate criminal minds of common folks. He would see it to prevail a general sense of chaos where people are not ruled by anyone or any sort of government but they are their own rulers. This will create an interesting phenomenon that without uplifting people from their poverty, lack of education etc., people will stop asking for anything but get themselves up and snatch their needs from the others. While this will ensue further chaotic society, none will be complaining. And then, again, this consistent chaos will start to crumble. So here I wait for another character or movie to simulate a chaotic society where chaos itself has started to crumble down…
