Was to make the political subversive come to love Big Brother. Only once he was cured, could Winston be executed. Once he loved Big Brother, he could be executed while his mind and his heart was pure. And The Party was therefore perfect, truly loved by all, even the dissidents.
So in Room 101, the point of the torture was to emphasize the fallability of the human body and mind. The ability of the mind and body to change it's perceptions was what Winston was taught through pain and mental anguish. And the main purpose was to elevate The Party to god-like status, given its immortality and unyielding "truth". "The Party is immortal," O'Brien said.
Much like those in the "reprogramming" in the Saudi case, where they are also fucked with until they have no idea what they are. It didn't get past me that this was not a "DE"programming, but a "RE"programming form of mind control. they just swap one cult belief structure with another, presumably beneficial one to the interrogators. The prole, or in this case the prisoner, is of no consequence on his own, but only as part of The Party does he have a life at all.
Hence my comparison.
