The quote highlights the idea that extreme political movements such as Communism and Fascism are driven by a deeper, more inherent malevolence within society. It suggests that these ideologies are not just isolated phenomena but are part of a larger pattern of collective behavior that embodies the loss of individuality and the acceptance of totalitarianism. The imagery of marching people, shouting in unison, underscores the danger of conformity and the suppression of personal beliefs in favor of a collective agenda.

This pervasive evil, as portrayed in the quote, reflects the human tendency to surrender personal identity and moral judgment to a group mentality. Kundera implies that this phenomenon is not just a political issue but a fundamental aspect of human nature that can manifest in various forms throughout history. It serves as a cautionary reminder about the importance of critical thinking and the value of individual voices in the face of overwhelming societal pressure.
