what is the restated thesis?

In conclusion Old Major had a vision that never came to be. After his death, it became twisted and perverted by those animals that got a taste of power and could not let it go. Instead of an animal utopia, pigs like Napoleon turned the farm into an autocratic dictatorship. Animals would senselessly and tragically die through a poisoned ideology meant for the self-gain of certain pigs. Orwell's Animal Farm hence becomes a cautionary tale of a utopian dream going wrong through human (animal) nature.
