This is not a route about villains. Villains are uninteresting — they know they are doing evil, and they do it. This route is about something else: about people who were intelligent, educated, sincere — and who caused enormous harm all the same. Plato worked out the theory. Robespierre carried it out. Nietzsche supplied the language. Dostoevsky saw the psychology. Marx built the system. Each of them, in his own way, answered one question: how does an intelligent man convince himself that he has the right?
Plato created the problem by trying to solve it. In the Republic he builds the ideal city: philosophers rule, because only they know the truth. And yet he himself describes how the philosopher turns into a tyrant: first he despises money, then the laws, then people. Plato traced the road from "I know better" to "I have the right" with merciless precision. He failed to notice that he was describing not the exception but the rule.
Robespierre read Rousseau as holy scripture. He believed in the general will of the people, in virtue as a political force, in terror and virtue being one and the same. "A revolution without terror is like rain without water," he said. Forty thousand executions in a single year. When the Convention arrested him in his turn, he was sincerely astonished: he had been doing good. The whole tragedy is in that astonishment.
Nietzsche did not justify evil — he analyzed it. Master morality and slave morality: the strong create values, the weak turn them upside down. This is not a call to violence — it is a description of how people convince themselves that they have the right. The tragedy: Nietzsche hated nationalism and antisemitism. His sister cut out the quotations she needed, threw away the context — and handed his texts to the Nazis. The idea outlived its author and betrayed him.
Raskolnikov kills the old woman with a clean theory in his head: there are ordinary people and extraordinary ones. The extraordinary — the Napoleons, the Mahomets — have the right to step across the law for the sake of a great goal. Dostoevsky shows: the theory holds exactly up to the moment of the blow. After it, only a trembling creature. He wrote this almost eighty years before Nuremberg. No one has described more precisely the psychology of a man who has convinced himself that he has the right.
Marx wrote: "revolutionary violence is the midwife of history." This is not a slip of the pen — it is a principle. If history moves toward communism by law, then everything that speeds the movement up is justified. The victims are the cost of progress. Marx did not want this and did not do it himself. But he gave the world a theory that allowed one to want it and to do it — with a clear conscience. That is the terrible power of systematic thinking.
How do you tell a person who is genuinely right from a person who has simply convinced himself that he is?
