O'Brien's Inner Party

O'Brien's existence by itself sort of gives lie to the whole activity right I mean a Lasso Bryan himself is somehow a big brother which maybe there's this kind of way in which all the O'Brien's that run the inner party are big brother in some way like they're all vegan but O'Brien’s activity requires him not to be the way Winston is at the end. I don't see how he can do the activity he's doing and be a broken man unless there's something about the love of power and the pursuit of power for power sake that animates him so thoroughly that he preserves his activity and is able to double think his way through existence.
