Creative thinking or an identity crisis?

Paul S. Sewell of Reading, PA signed his voter registration, PA driver's license, and the back of his credit card all with the name "God". He claims it's the same as leaving an X as a mark. The idea came because he is a bounty hunter and the fugitives often say things like "Oh, God, give me another chance!".

Is this just an amusing way of expressing himself, or is it a blasphemous psychological problem? Only Sewell knows for sure.
