The animals in Animal Farm don't have much in the way of food, dignity, or leisure—but they do have pride. They take pride in banding together to overthrow their first oppressive leader, and that common feeling makes them willing to endure their second oppressive leader. Napoleon is smart enough to use that pride to manipulate the animals into obedience and then to convince them that the whole system isn't just failing and corrupt. And… it seems to work. Hm. We feel like this is a good lesson for our ultimate Internet takeover.
While the pigs use pride to control the other animals, their own pride controls them in much the same way.
Pride initially sparks the animals' rebellion, but it quickly becomes just another tool of oppression.
