What is unclear to me about The Stranger, is whether any element of sacrifice is included at all. While Meursault is very easygoing and tends to go along with any plans his friends have, by no means is he selfless. He does things that other's tell him to simply because he has no reason not to. He doesn't help Raymond because he firmly believes in their friendship or in order to save him - he is even somewhat annoyed when Raymond calls him "pal." He helps Raymond with an attitude of "Why Not?" This attitude carries throughout the novel, coming off as apathetic and indifferent. Meursault does not sacrifice anything for anyone- evident in the fact that he is peeved by how long the journey is to his own mother's funeral. Because this novel is written in first person limited, we are restricted to only Meursault's thoughts, making it very difficult to understand the human nature of other characters in this novel such as Marie, Raymond, and Salamano.
Perhaps the absence of any sign of altruism is Camus' way of expressing that he thinks sacrifice, especially religiously speaking, is not necessary to the functioning of society. (this is also seen in the way Camus' portrays the Chaplin as over the top, narrow minded & judgmental.)
While Camus' uncovered many universal truths and exposed the judgmental aspect of human nature, he did not even address the theme of sacrifice. So, in relation to my big question, I began to wonder, can there be a world without the existence of sacrifice?
