George Orwell's novel 1984 demonstrates how a person can be completely changed. Winston Smith the protagonist in 1984 was completely changed by the end of the novel. The government transformed Winston's beliefs from despising to loving Big Brother. By the end of the novel Winston was fully transformed, his way of thinking was altered and he was brainwashed into loving Big Brother for the rest of his existence.
Winston has been tortured, in the Ministry of Love by O'Brien for days, maybe weeks or months, we never know. As the torture takes place he never becomes fully transformed until he loses the ability to love. At a certain stage during his torture Julia was the only thing he still loved. She was the only person that stood in the way of Winston loving Big Brother. He mentioned earlier in the novel that his love for her could never be broken, they would never be able to separate and he wouldn't be able to live with out ever seeing Julia again.
O'Brien asks Winston and Julia, "You are prepared, the two of you, to separate and never see one another again? No broke in Julia. It appeared to Winston that a long time passed before he answered. ... No he said finally" (Orwell 142-3). The reason that love kept him from being fully transformed to what the government wanted him to be is that he is not suppose to feel love for anyone but Big Brother and the party. Julia is the only person he loves and until he betrays Julia and feels no love for her, he has not been fully altered into what O'Brien and the government want him to be. The
