I would say that playing this character has caused me to think about a lot of things. He's always questioning himself and trying to get back to something he lost touch with and trying to find forgiveness. Everybody struggles with these things to some extent in their life.
But in the end in the end one is alone. We are all of us alone. I mean I'm told these days we have to consider ourselves as being in society... but in the end one knows one is alone that one lives at the heart of a solitude.
