Directly related to the idea that the rulers of the rebellion the pigs eventually betray the ideals for which they presumably fought, this theme is dramatized in a number of relationships involving the novel's human characters.
Therefore, Snowball is depicted as a creator hero. It was made into an animated movie in One day, Boxer collapsed while pulling stone for the windmill.
After the rebellion took place the animals put in writing the Seven Commandments by which all of the animals would live.
They also came up with Seven Commandments of Animalism.
It was said that Snowball was the leader of the humans. This was the beginning of their abusing of their power. As for the dogs, when they grow old and toothless, Jones ties a brick round their necks and drowns them in the nearest pond.
Anytime they confronted the pigs, they were always given some excuse or reason why things were not the way they were supposed to be. Particularly, the novel focuses on their ability to manipulate their citizens for their personal benefit.
Religion and Tyranny Another theme of Orwell's novel that also strikes a satiric note is the idea of religion being the "opium of the people" as Karl Marx famously wrote.
Another example of violence is when Napoleon commanded the dogs to chase Snowball off of the farm.
