Explanation:
The chief difference between Old Major and Napoleon is that Old Major truly believed in the ideal of the animal revolution he envisioned, whereas Napoleon cynically used the revolution to gain power for himself alone.
Old Major is based on Marx, and he truly believed that the animals could have better and easier lives if they would take over Mr. Jones's farm and run it themselves. He believed in using the profits for the good of all the animals. He believed in the animals working together in solidarity to build an idyllic future in which all would share the rewards of a just society. He cared about his fellow animals.
