Darum (2008)

Think of a really nice person, a friend of yours, someone who could never hurt a fly. Imagine finding out that he is supposed to have killed someone. You're told that he has shot a person in a bar, for no obvious reason. He has already confessed. He says the murder was planned. He expects a life sentence. He even longs for it. He wants to pay for his crime. The psychiatrist cannot see any mental illness. People around him don't think him to be evil. They like him. They want to help him and protect him from himself. And they all ask the same question: Why....?
