In what way is Snowball corrupt?

The only way Snowball can be deemed corrupt is to mention that he, as much as the other pigs, enjoyed the benefits that they, as leaders, unfairly and undemocratically, allocated to themselves, excluding all the others. A good example of this is when the pigs claimed the milk and windfall apples for themselves, supposedly because it was 'brain food' and enabled them to perform their tasks well enough so that Jones would not return.

The only way Snowball can be deemed corrupt is to mention that he, as much as the other pigs, enjoyed the benefits that they, as leaders, unfairly and undemocratically, allocated to themselves, excluding all the others. A good example of this is when the pigs claimed the milk and windfall apples for themselves, supposedly because it was 'brain food' and enabled them to perform their tasks well enough so that Jones would not return. This was the propaganda spread by Squealer and which the other animals accepted without question.

If Snowball had been a committed believer in the principles of equality, he would have opposed the reservation of these for the pigs' exclusive use. He, instead, said nothing about it and partook of these benefits just as much as the other pigs did. It is obvious, however, that in a general sense, Snowball had the well-being of all the animals at heart and consistently worked at improving conditions for them. He established numerous committees and worked extremely hard at educating all and sundry.

Snowball also introduced a number of innovative ideas in an attempt to make life easier. His outstanding achievement was the design and planning of a windmill which would provide electricity and ease the lives of the animals tremendously. Sadly, though, Napoleon opposed all these ideas and even went as far as urinating on Snowball's plans. On the day Snowball presented his ideas, the sly Napoleon called upon his guard dogs and they chased Snowball off the farm - never to be seen again.

Subsequently, Snowball was used as a scapegoat for everything that went wrong on the farm. Through misinformation and propaganda spread by Squealer and Napoleon, Snowball was thoroughly demonized and was eventually seen as a threat to the safety and security of the farm. Napoleon used his name as a scare tactic and also to execute those who had supposedly been secretly plotting the overthrow of the farm with him.

In the end, therefore, everything about Snowball's good deeds came to nothing for his name was blackened and he was seen as a pernicious villain. Napoleon could then exercise his will on all the animals and, since he was unopposed, became a tyrant.
