Mad mans memoirs

You can read the book. Or play the game. Or both. The book contains a mad mans words and thoughts as he is incarcerated waiting for his penalty to be executed. But he is innocent, in his own point of view. Having done exactly what he is accused for, but unable to see that it is something wrong or bad to liberate the world and try to get people to wake up. Compelling arguments and different perspectives are presented. Is he right, or wrong? Or is there even such a thing as right or wrong? Doesn't it depend on the perspective? Perhaps you have one view as you start to read this, and another as you are done? Who knows?
