In this case, IMHO, a very great deal of what was in this certainly belonged there, if it was to be a study of a character. There was way too much in there as it was, however, and a vast range of things had to be left out or mentioned in passing.
That is one criticism I’ve heard: trying to put too much into it. And as a result, there was not enough focus on any one thing. For myself, I’m more interested in the official history of Napolean than in his personal life. I wish there would have been more of that.
