Winston thinks he is making progress. he is learning to practice crimestop. what is he learning? what is he hoping for?

He’s being re-brainwashed into loving Big Brother, and learning how to turn others into the Ministry of Love, by detecting thought crime. He hopes to become thought police like O’Brien.

Crime-stop is to keep individuals in line, and destroy anyone that might kindle are bellion against big b rother.

When Winston and Julia initial meet O’Brien, he asks them to conform to do something they're told to try and do, together with committing murder, activity sabotage that might cause the deaths of many innocent individuals, and throwing acid in a very child’s face. They conform to everything except separating and never seeing one another once more. It appears that if big Brother can do something to remain in power, the Brotherhood can do something to defeat big Brother.
