As I have read the Book of Mormon multiple times, I have gotten to see Mormon's narrative more clearly and thought about how and why he chose which stories and which things to include. It has helped me to know him a little better. And Moroni is little bit of an incredible mystery too. They tell us all about the other people, but we have to learn about them by what they chose to tell us about others. Like Moroni choosing to add Mormon's two talks in Moroni 7 and 8, that Moroni decided to add after he had finished the record several times. Moroni 7 is one of my favorites, so I am grateful to him for including it.
