The whole moral of Animal Farm, is that there will always be tyranny, even in Socialism, and that socialism will always turn into communism.
Explanation:
We see this in Animal Farm, because after the animals took over, they promised that everyone will be equal. But the pigs ended up going back on their word and took over. Than they told everyone that they were more important than everyone else.
I would say pessimist. In "The Great Gatsby", Gatsby never ends up getting Daisy. He loved her, but all of his efforts were wasted. She never loved him back. I hope this helps!
