Moroni Mormon, Ether and Moroni, The Book of Mormon

The Book of Mormon has two prominent characters named Moroni. The first is chosen at a young age to become a military leader. The second, who may have been named for the first, lived about five hundred years later. He also serves in war when his people, the Nephites, are in danger of annihilation at the hands of their enemies, the Lamanites. His life is lived during the 4th and 5th centuries A.D. Moroni may have spent most of his life in Central America, though that is not confirmed by the scriptural record itself.
Moroni courageously carries out his military duties, but the numbers favor the opposition, and the Nephites, because of their own corruption, have lost the help of the Lord, much in the way of ancient Israel and Judah in the Old Testament. The scenes of his early life must have been horrific, as the slaughter of his people  leads to their final disappearance from the earth.
Moroni himself somehow outlives most of this, and he takes up the most important work of  his father Mormon's life. That work is abridging most of the records comprising the current Book of Mormon. Moroni proceeds to finish the volume.
This latter is no easy task. Moroni is, by this time, a hunted man. Both his days and night are, as far as we know, spent in complete solitude. He probably was obliged to move often and quickly, seeking safety. Could he build a fire? Did he have time each day to add to the record, or did he have to abandon it from time to time just to stay alive? His own record says little about the conditions of his later life, but he evidently had to live this way for decades.
When he does have time to write, it is not on paper, but on thin plates of gold, a process no doubt much slower than we can manage with a pen or pencil. He finishes the part of the volume known as the Book of Mormon (relating specifically to the life of his father), then takes up the task of abridging the record now called the Book of Ether, and finally, somewhat in the style of an appendix in a work of non-fiction, leaves some evidence showing how his people had once lived, both successfully, and as their society declined and, finally, disappeared. This last part is known as the Book of Moroni.
It would be easy to see how someone in these circumstances might become cynical, hateful or even crazy, but that isn't the case with Moroni. Even left alone, he looks toward the future and wishes the best for people of future generations. He never ceases to express Christian love for people he will never meet, and leaves to them, the people of  the era since the Book of Mormon was first published in 1830, the challenge of reading and pondering the contents of the book to see if it carries the weight of truth. Millions of people have done so, using  Book of Mormon versions which are now translated into dozens of modern languages. Having read the record, many have been willing to make enormous changes in every aspect of their lives. For his part, Moroni's statue is found atop all the temples of the Church of Jesus Christ of Latter-Day Saints throughout the world.
