This is a biography of cope. Steven D. Kelley is ~Christian and throughout is doing mental gymnastics to cope with the fact that as someone who was an innovator in weapons manufacturing he is somewhat responsible for a lot of death. For example he claims that laser gun sights he produced led to fewer deaths bc people would see the dot on themselves and surrender LOL. He also repeatedly exits the industry bc of the guilt only to join again. The interesting parts of this book total ~5 pages and it's hard to tell if this is sloppy disinfo or if he is nuts.
Also I know nerds that write books are worried that people will think of them as stereotypical loveless losers but dedicating a large % of your book to reassuring us that you're a ladies man that gets laid all the time is cringe and insecure (looking at you Feynman) Stop it.
