Striking Moment in The Stranger by Albert Camus

One passage that struck me as odd in the opening chapters of The Stranger occurred on page 28, "And once he [Raymond] asked me, talking about Salamano, "If that isn't pitiful!" He asked me didn't I think that it was disgusting and I said no".
I thought it was surprising that when Meursault was asked what he thought about a man abusing an innocent animal he replied hat he did not have a problem with it. I feel like animal abuse is a pretty commonly opposed issue so the fact that he wasn't bothered by it surprised me. Furthermore, Raymond had thus far been described as a pretty bad guy, so the fact that even he was bothered by the animal abuse and Meursault was not is surprising. I think that this section shows a lot about Meursault's character and his indifference towards other people and life in general.
