Would you ban a particular type of movie because it will have a bad influence on one person?
Let's say you were going to make a fictional movie about crime, a "crime thriller," something like the new "Jack Reacher" by Tom Cruise. Let's say you knew a million people would find the movie entertaining and somewhat stimulating. But you also knew the movie would influence one person to go out and commit a crime. Would you make the movie for the sake of entertaining the one million, or would you refrain in order to prevent the crime?
