Give one example of a theme in Animal Farm?

Most of the episodes can be related to the Russian Revolution, but the power of the book is not as a simple parody: it lies in Orwell's message about the seductive nature of power and the flaws of human nature. Snowball undoubtedly worked for the good of all, but that did not stop him welcoming the rewards of power. On the other hand, Napoleon is described at the start of chapter two as "not much of a talker, but with a reputation for getting his own way", suggesting that there may always have been something selfish about Napoleon. By contrast, we feel intense sympathy for the downtrodden animals, particularly Boxer.
