Twitter was recently dragging Orwell, pointing out that Animal Farm and 1984 are awful books in which people are mean and evil because people are mean and evil. Orwell definitely had an axe to grind: the hippies lost the Spanish Civil War and the proles refused to honor the monarchy. "Bad people are bad" is a mathematical identity of our collective human monomyth. It makes for easier stories. "Conquistadors wiped out South America because they are bad" is much simpler than "privateers and adventurers with no treaty authority overreacted violently to an overwhelming military force desiring to sacrifice them for faction cachet within their own civil war". Our moral teachers cannot make their point if you start from the standpoint that everyone is a hero in their own movie.
