The complexity of Meursault

"But Raymond told me he didn’t think he could write the kind of letter it would take and that he’d thought of asking me to write it for him. Since I didn’t say anything, he asked if I’d mind doing it right then and I said no... When he told me the woman’s name I realized she was Moorish. I wrote the letter. I did it just as it came to me, but I tried my best to please Raymond because I didn’t have any reason not to please him" (41).  Camus effectively expresses the confusion of what Mersault's motives are through this passage. When Raymond first tells Meursault of his dilemma, Mersault seems indifferent and doesn't care too much about it as he was unwilling to write the letter for Raymond. However, he then suddenly wanted to write it and attempted to impress Raymond without any reason to. Camus does a good job of making simple text with a complex meaning. What is Mersault's motives? Does he want to write it because she is Moorish? Or just out of boredom? Camus allows the readers to open their mind to different possibilities and decide for themselves why Meursault actually wants to write the letter. For me I first believed when reading the text that Mersault was prejudiced towards Moorish people. However after thinking it over, I feel as though it could be perceived differently. Maybe after drinking Mersault just decided to 'screw it! I'll write it!' However there is no right answer, it's for the readers to decide for themselves.
