Compare the lives of animals when they live under Jones and under Napoleon. In what ways Napoleon has proven himself a similar tyrant?

The animals actually live worse under Napoleon than they did under Jones. Once the pigs find out the delights of such things as sleeping in beds, they take everything for themselves, punish the animals when they get out of line, and generally keep their lives away from the lives of the other animals. We know how bad it has become when Boxer, who can no longer work, is sent away to be slaughtered.
