Fear is a powerful emotion that the Party uses to change independent thinking. Fear pushes Winston to act on emotions rather than instinct. He desperately wants to reveal his feelings to feel relief, but the Party's fear of punishment hinders him. The Party uses fear on Winston to scare people like him into taking action and this allows the Party to maintain power. Although he wants to assert his individual nature against the Party, he is reluctant due to his mentality full of doubts and worries. The Party also uses fear to maintain power by distorting human reason. Winston is captured by O'Brien where he experiences physical pain and horror in Room 101. When O'Brien brings a cage of mice and tells Winston that the mouse mask will be put on his face, he shouts at Julia to do it: "I don't I do". no matter what you do to her, tear her face off, strip her to the bone” (Orwell 286). Winston is one of many who manage to challenge the Party but out of fear it interrupts his act with torture and pain. The Party is intelligent and knows that with fear it can disturb the logical reason to control its citizens. With fear the Party manages to appear powerful and unstoppable and willing to go to extremes to maintain power. Winston's fear of rats and pain also force him down a path he doesn't want to follow but with his mind overwhelmed he is unable to act on his desires. The fear that the Party has used to maintain power is a great asset for Big Brother. It limits citizens from challenging the government and thinking for themselves. Without fear the Party would have weakened, but with fear they managed to use it in order to maintain it
