The song "Et quel crime?" by Daniel Darc is a poignant reflection on the pain and suffering caused by crime, betrayal, and despair. The lyrics express feelings of guilt and remorse, as well as a sense of hopelessness and longing for release from the burdens of life. The song evokes a sense of loss and abandonment, with the singer questioning what crime or betrayal led to the devastating outcome of a loved one leaving. The imagery of a "wagon gris d'avant-guerre" (gray pre-war train carriage) and trains that "vont nulle part" (go nowhere) creates a haunting and desolate atmosphere. The refrain "Suis-je le gardien de mon frère? Son sang hurle de la terre" (Am I my brother's keeper? His blood screams from the earth) reflects the anguish and responsibility felt for the pain and suffering of others. It also alludes to the biblical story of Cain and Abel, where Cain famously asks God, "Am I my brother's keeper?" Overall, the song conveys a sense of despair and a longing for redemption and release from the burdens of life. The haunting melody and introspective lyrics make "Et quel crime?" a moving and thought-provoking reflection on the human experience.
