George Orwell's book, Animal Farm, is a great book. However, the characters that the pigs portray are cunning, sneaky, and sly. The seven commandments, which are the foundation of their society, (p.21) will all be broken in time. The three most important, to me, are the commandments stating, no animal shall kill any other animal, no animal shall sleep in a bed, and all animals are equal.
No animal shall kill any other animal. This was commandment number six. No one ever imagined it would be broken, let alone by their leader, but it happened. Napoleon, in an attempt to maintain total control of the farm, killed four pigs, which he forced to confess to a heinous crime of treason, which was punished by death (p.75). No animals objected to this breach of commandments. The next time the animals should look at the seven commandments on the wall, they would see commandment number six as, No animal shall kill any other animal without cause. .
No animal shall sleep in a bed, was commandment number four. This commandment was agreed upon by all of the animals the day of the revolution unanimously. However, the pigs, feeling superior, would then sleep in these beds (p. 60-61). The pigs claimed that, as the brainworkers, of the farm, they need this rest while they despise sleeping in a bed. They say that even though humans sleep in a bed, they use sheets while the pig do not, which is the main difference in their beds. When seeing the commandments again, the animals read commandment number four as No animal shall sleep in a bed without sheets. This is different then the animals remember, but without proof, they will not say anything to Napoleon.
All animals are equal, reads commandment number seven. This is one of the last commandments to be broken (p. 118), but it is the most influential. The first step in this was to take the pigs away and teach them to chant "Four legs good, two legs better," instead of the old chant, "Two legs bad, four legs good.
