I think that Orwell uses Winston to speak out about his own strife with governmental power. Remember that Orwell wrote 1984 during a time when the world was at war (World War II). Orwell also had experience being a soldier fighting for a cause he believed in during the late 1930s in Spain. During World War II the country faced the evil powers of Stalin an Hitler- Orwell uses this dark story to illustrate his feelings about giving a government, dictator, or group of people too much power. Winston tries to warn us to never forget to think for ourselves and to always be expressive even in the face of being different. It is important to always question the powers that be, no matter who they are.
