Was George Orwell a supporter of joseph salin and wrote Animal Farm as propaganda to support stalinism in the former ussr?

George Orwell refers to Stalin as a "disgusting murderer" in his diary, so I think it's safe to say he wasn't a supporter.

Animal Farm is, if anything, a ringing condemnation of Stalin's brand of socialism. Again, if it was intended as pro-Stalin propagana, Orwell was singularly bad at it.
