You make a very good point my friend. Now this the main reason as to why he decided to write 1984, and it is very true that INGSOC, stands for "English Socialism", but it wasn't because Orwell completely changed political views is why he wrote it, it was because he now realized and saw for himself that both sides of the political spectrum can have it's evil and corrupt sides, he wrote the book as a warning to people, to be aware of these dangerous potential that can be brought from socialism, nationalism, communism, fascism, all political ideologies should never be completely trusted, for every ideology will have it's dark side.
