It is right that true story life of criminals or villain be shown in a movie?

Two Answers:

1. Not as fiction, no. Fiction is to be about someone who during the film's timespan tries to do the moral-ethical rights thing and succeeds--whether he wins the day or not.

Clint Eastwood in Absolute Power is an example--career criminal--but he does the right thing at every point after his robbery is interrupted.

2. Not as Non-fiction no. What's the point? You can always have a criminal as a character, true life or not, but what's the point? lessons to potential imitators? What's the value for a normative in watching such things? A book can dwell on the wrongness of the person's acts, and keep context. No way in which a film for me can do that.

Thanks for asking
