Winston wondering what O' Brien could possibly have to frighten him so much to the point that it is torture is threatened; O' Brien pulls out a cage of hungry vociferous rats and threatens Winston with allowing the rats to eats and gnaw on Winston's face. Knowing from previous times, Winston terrified by rats is almost at breaking point. Winston horrified by the rats being just inches away from his face Winston cracks and screams "do it to Julia" giving out. O' Brien is satisfied with Winston's response to the rats because that betrayal means there is no more private loyalty which leads only to loyalty to the party and Big Brother.
In book three chapter six months have passed and Winston is in the Chestnut Tree Cafe where other dismissed party members go to drink victory gin. At this point Winston accepts all of what the party says and all that the party does. Winston remembers a cold bitter day in March of 1985 when he saw Julia again; Julia was stiffened, her physical features where where roughened and the tortured endured had effected her face and more. They had spoken of the mutual betrayal and how torture can impact people to the point of change. They agreed to meet and what not, but they would not continue their relationship. Winston later feels sorrow and cries when he remembers how his life was with his family, his mother and sister. He sits and wonders whether it is true or not and then hears the parties propaganda coming from the telescreen in which now he believes. Memories of the Ministry of Love makes Winston wish to die. Winston looks at the big Image in the telescreen of Big Brother which makes Winston feel joy due to the love he now has for Big Brother. He is happy for achieving victory over the traitor he once was.
Everyone has a breaking point that when is found, anything can be taken from that person. Torture can be performed in many ways, some more effective than other but all for the purpose of getting something from the person being tortured. Torture is the use of physical and psychological pain to control the victim or fulfill some needs of the perpetrator. Once somebody is pushed to their breaking point by torture not only can get information out of them but it effects the physiologically from then on. Depending on the extend to which the person was tortured people can be changed as Winston was by O' Brien. According to studies, torture can damage people not only physically but physiologically, which majority of the time leaves permanents scars that change people. Torture can be used as a form to manipulate people due to the physiological damage cause to the individual person.
This is a boring ending to the book. The party wins and Winston is too weak to even have had a chance to last and succeed in his goal of overthrowing the party with and making the proles see the reality of the party. There is nothing left of Winston to attempt to overthrow or even have the slightest idea of going against the party. Julia is even weaker, from the beginning she had little interest in going against the party and overthrow, she just liked being against the party "from the waist down" as Winston had said.
