I think we all suffer from guilt at some point in our lives but for the most part I never really regret and I try to always remain positive. Yes I think that those issues are very interesting to play in a character and they're prominent issues in life and I think people can relate to them.
When I work alone it can be like dabbling with a canvas. Maybe you paint over bits and it starts to form its own life and lead you off in a direction. It becomes an intuitive subconscious process.
