Only humans violate the way of heaven: creating more species, and males are still responsible for nurturing. Essentially: it is a lie told to discipline men.

Returning to biological origins, the fundamental logic of male animals is "just sow, not ask for harvest, and even less responsible for nurturing."
Years later, looking back at human history, you might find that those seemingly responsible men are actually the real "scumbags" who betrayed the laws of nature.
