I'm not sure how you interpreted my post as him simply sucking, but that is not what I meant. I attributed this quality to his past, which has made him what he is now. If you notice, he has a certain lack of concern about his own well being, especially when it comes to doing his job (in this case, keeping Murasaki out of harms way). This pride issue is simply a part of that. I'm sure it will be elaborated on later.

About him teaching Murasaki a lesson, while it is possible, from his facial expression I kind of doubt it.
