You're analysis is very similar to one I gave a couple years ago. He had a wide range of knowledge and skills. Maybe "death wish" was a misnomer...I didn't mean that he literally wanted to die...but He seemed to tske self sacrifice to an extreme. And he started out that way. Whereas Hoshi began as a more timid, fearful, uncertain person. It always confuses me as to why Malcolm was only a lieutenant. It seemed to me he should've been at least a lieutenant commander .
