Die Sonate vom Guten Menschen ( Sonata for a Good Man)

Me playing Die Sonate vom Guten Menschen from the film The Lives of Others composed by Gabriel Yared. (From the scene where Georg Dreyman Finds out his good friend Jerksa has hung himself. He sits down at the piano and plays this piece, as Stasi Hauptmann Gerd Wiesler listens in and is moved. ) Can anyone who has heard this music, I mean truly heard it, really be a bad person thanks to andrewpn for the sheet music
