Meursault- A stranger to feelings

The main character, Meursault,  in Albert Camus, The Stranger puzzles me because  he seems to have no feelings of love or affection. He finds  out about his mothers death in the beginning of the book and focused on just the details of going to the funeral and about traveling. Then he doesn't seem sad, or cry at the loss of his mother. He is emotionally withdrawn from his girlfriend. He kisses her and has lustful feelings towards her, but is indifferent about their relationship. He is also noncommittal with his friends, but they seem used to it, unlike his girlfriend. He's similar to the robot women he encountered, robots have no feelings. In the shooting scene in the book Meursualt shoots the Arab at the beach, he seemed disconnected from his feelings. He describes in detail the sun, the sweat in his eyes, the physical sensations, but not the emotional connection to hes actions. One would think that you would have a lot of rage to take a life. He didn't seem that upset. There's a connection to temporary events in the news- Laquan McDonald who was holding a knife was shot multiple times by officer Van Dyke.
