Unforgiven. That was the image that lay in my head. I had seen the movie 'Unforgiven' a couple of years back. Directed by Clint Eastwood and starring Gene Hackman, Morgan Freeman, Richard Harris and Clint Eastwood himself, it deals with the man and the myth in all those tough western movies.
It begins with the Clint Eastwood digging his wife's grave below a tree, the woman who reformed him from the thief and murderer that he was. The movie ends with him standing below the tree at his wife's grave. Unforgiven, is about forgiveness and the lack of it. An insight into the movie can be found here.
