The Stranger Chapter IV, V, and VI.

I really hoped that by reading the book further something would happen, and I would realize what makes Mersault behave like this. He is so cold, he does not show any sign of warmth within his heart. However, there is something that makes me think that he has a little bit of emotions, even though he does not express them. The appearance of Marie in his life, and the feelings that he expresses (but not quite often) make me believe that still, he has something in his heart, not only coldness and darkness. Still, he does not seem to care much for Marie, to him it is really the same whether he marries her or another girl. He does not even care about the fact that he actually killed someone, to him it was all calm, like something that life gives you everyday and not a murder of a human being. He seems to be the kind of person that does not doubt much about what he does, and what his future would look like. He lives for today, and takes the things as they come.
I really wonder what kind of person he is, because from what I read until now, it seems like he has a very disordered personality.
