Why does Alex Choose to Be Evil ?

Alex thinks that "badness" is human nature .Any government that prevents its citizens from doing bad things refuses to let them be human. Alex likes doing bad things because they bring him pleasure. He feels that it his right to indulge his primal desires; it is his right to take pleasure when he wants. The moral middle-aged “bourgeois" impose a sanitary value system on others; it is a value system void of pleasure.
