That is the shtick of Inspector Barnaby in Midsummer Murders: a police detective with a happy home life!? Radically different!This is a trope common throughout literature of all genres and all ages.
Broken people are generally more interesting than folks with little to no trauma in their background.
And IRL, everyone has trauma. Different kinds and to different degrees, but it allows us to empathize with the broken hero trope.
If that guy can overcome his demons, maybe I can too! My family wasn't murdered by a flight of dragons while I watched, we just grew up poor!
