characters and writers

While in many cases the writer does express his/her own opinion in their characters, not all writers will do so. If a writer believes in one thing, but the audience that they are writing to believes in something else, then they may have a character embodying the consumer's belief rather than their own. Some writers write solely for the money, and so are willing to express (even to the point of supporting) another's ideals if that means they will make more money. Usually, i think that this would only be done when comedy is concerned; unless of course the writer believes mass murder is ok or something, then they would write characters that do not embody their beliefs for the sake of pure reputation i suppose.
