What theme is primarily explored through the commandment changes in "Animal Farm"?

The theme of corruption of power is primarily explored through the changes made to the commandments in "Animal Farm." As the story progresses, the pigs, who assume leadership roles, begin to manipulate the original principles of Animalism to justify their increasingly oppressive actions. The gradual alteration of the commandments reflects the way those in power can distort ideals for their own benefit, leading to a betrayal of the initial revolutionary goals of the animals.

For instance, the commandment "All animals are equal" transforms into "All animals are equal, but some animals are more equal than others," showcasing the shift from equality to a hierarchy that privileges the pigs. This corruption not only highlights the dangers of unchecked authority but also serves as a critique of how revolutions can become co-opted by those who seek power above all else. The alterations to the commandments symbolize the moral decline and ethical corruption that often accompany the pursuit of power, illustrating how leaders can manipulate language and principles to maintain control and justify their actions.
