Characterization of the character Napoleon

Napoleon is a big, impressive berkshire boar. After the reign of Mr. Jones he instantly tries to take a high position on the farm. But Snowball, a very smart and popular pig, who took very good care of the needs of all the animals stood in his way for. Napoleon wanted to be the almighty animal on the farm so he violently took over the farm.

The longer he was in power, the worse his personality became. He never had enough power, he always strived for more. Every animal had to do exactly what he wanted. He was a ruthless leader and all the animals on the farm had to suffer under his regime.
His greed could not be satisfied, he always wanted more and more. He exploited the other animals for his own needs and showed no compassion. He also didn't take responsibility for his mistakes. Everytime something went wrong, he blamed Snowball for it. He said Snowball would sabotage the Animal Farm. But this wasn't true. He spread lies about Snowball, so the other animals wouldn't remember what a good pig he was and how good the life on the farm had been when he was still in charge.

He was extremely egoistic and racialist, because only the animals of his kind had enough food and freetime. However he could manage to stay in charge as the leader of the farm because he was very good at manipulating others.

He was narcissistic and he used every means to get what he wanted.
