The end of part one ends with Meursaults overkill of “the Arab.” I was confused as to why Meursault even shot the Arab once because the second time Raymond and he encounter him, Meursault keeps Raymond from shoot by saying, “It’d be pretty lousy to shoot him like that” (56). This seems to be one of the first times, if not the first where we see an ounce of morality in him. He understands that it would be wrong for Raymond to kill this man both because the man doesn’t deserve to die and it Raymond would face consequences.
However, once Meursault is handed the gun for safekeeping, he suddenly has this big realization that whether he kills the man or not kill made no difference in his life or in the world with the line, “It was then that I realized that you could either shoot or not shoot” (56). Although I want a different answer this line seems to show that Meursault killed for no apparent reason at all. He was indifferent to the shooting.
Except why 4 more shots?? He say’s it was like “knocking four quick times on the door of unhappiness”(59). Maybe in this instance Meursault was trying to feel some sort of feeling (unhappiness) for what he had just. He knows that his indifference to everything is not normal and deep down wants to feel something even if it’s negative.
