Is Meursault really in charge?

In the book The Stranger, Meurasult shows he has no emotion towards other peoples feelings. Meursault is the type of man to react to a situation the opposite way you would think. When his mother died, he didn't cry at her funeral and when Marie asked him to marry her, he said "sure". Meursault didn't care what really happened because he is so focused on his own life and just goes with the flow of things. I think that the reason Meursault never really lets anyone into his life is because he always wants to feel in control and by letting his guard down and his emotions out, he doesn't feel in control and that control keeps him going. Meursault believes that life is meaningless or I think he would have stood up for himself more when he was in court.
