Hannah Arendt in her study of totalitarianism borrowed from Immanuel Kant the concept of radical evil, of evil that's so evil that in the end it destroys itself, it's so committed to evil and it's so committed to hatred and cruelty that it becomes suicidal. My definition of it is the surplus value that's generated by totalitarianism. It means you do more violence, more cruelty than you absolutely have to to stay in power.
