Society in Brave New World is much different from the society we live in today. Individuality is not to be expressed and having different morals and a sense of uniqueness sets you apart from others. Bernard was one who was specially fit for the alienation of others. Bernard is a little different from the others and being different is not acceptable especially in the eyes of the government.
Bernard possesses strong characteristics and valuable morals however he was exiled from the world state due to the fact that he doesn't always go along with the normality as the rest do. Bernard knows right from wrong and will admit when he feels he has done wrong. The World State is often caught by surprise when it comes to Bernard because he strays from the norm and doesn't see the use of drugs and sexual behavior as a way to live everyday life and it is not something he views as "self- respect" which shows a lot about his character and life values.
Bernard never developed to the structure of his caste level which strongly set him apart from all the other Alphas. Bernard was alienated due to the fact that he did not fit in with the rest of society due to his unique appearance when compared to the other Alphas. In order to fit into society you can not be an individual you have to basically be a clone and very much similar to everyone else in your "social caste" or else you will be alienated and society will not accept you. Society does not believe in the thought of "daring to be different", being different sets you apart from every one and you will not be welcomed by the World State. The World State is set on what it believes and possessing different qualities sets you apart from the rest.
Overall, being your own person is not valued in the World State. Possessing qualities that do not go along with the rest of society makes and an outcast automatically and you will most likely be exiled. Society doesn't look past the differences to try to see what kind of person Bernard is. Bernard is judged based on his overall appearance and morals which in the World State is totally acceptable and a normal part of life.
