You cannot break human nature through political coercion. Human nature is largely dependent on culture, which is a product of centuries of intellectual, religious, and materialistic endeavors. It may bend when political coercion is applied, but as soon as the political coercion is removed, human nature will, like a spring, revert back to its original shape. However, human nature can be broken by attacking and transforming culture. That is why the philosophies and political movements that want to promote a different type of human beings despise the existing culture—their politics centers on erasing the old culture to make space for a new one.
