Albert Camus's works are philosophical allegories that explore, primarily, human evil and inherent sin nature. The three works chosen here all have overarching themes of violence, desolation, and despair—a commentary on Camus's own life, which was marked by existential angst, multiple failed marriages, and much personal turmoil. In "The Stranger," Meursault murders an Arab man in the desert after a prior conflict. In "The Renegade," a former missionary is abandoned in the desert with his tongue cut out after attempting to assault a woman. Both of these situations display violence and use the desert landscape to explore it.
Camus's utilization of the desert explores the idea of moral destitution and solitude. These men in the stories have no life morally (there is nothing blooming or good in them morally), and they are alone without help and without guidance from an outside moral source. This is a reflection of Camus's existentialist beliefs that the world is fraught with evil and there is no salvation or anything good to be found.
