Marquis de Sad. The great libertine, a scandalous novelist or a dreamer-warrior?

Marquis de Sad - a genius or a simple lecher?
How immoral is the preaching of complete freedom - without "brakes" of religious and ethical rules developed by millennia?
Now it will seem to someone that such "brakes" violate human rights. But it was to this that he called on his life and books by Donasyen de Garden two centuries ago - to the fact that today, alas, it has turned into stereotypes of mass culture, which we no longer notice, although the name of this person gave rise to the term “sadism”, indicating an unacceptable Unmotivated cruelty. So what, in fact, devoted his life to the notorious Marquis, paying for his addictions an enchanting series of arrests and movements from one prison to another? Maybe he just absolutized some ordinary moments of love games? Or do we not know any secrets of this person yet?
