Query: Not a good movie

Why do you need to invert the characters make good characters bad and the vilest (but very bright) John Silver good?The book is about a few good people, because of their discipline, faith and sense of duty, prevailing over many criminals.The movie is about moral equivalence. It can be compared to a movie about 9/11 making bin-Ladin a good guy and president Bush a bad one.
