A Movie Request: People Never Change?

Question by : A Movie Request: People Never Change?
I am looking for a movie that shows that people never change. I was thinking something along the lines of a criminal who means to change but keeps making bad decisions. It doesn’t have to be about a criminal just a movie, any movie, that has the theme (even if very minor or for one character).
