Thinking of uncle's childhood makes me crazy too bc there isn't any backstory but we probly know everything we need to know. people usually just act out to their children the things that were done to them as a child. going with the theme of family inheritance passed down to Julien, Uncle likely had his own "uncle" growing up
also crazy to think Uncle was alive maybe when Doc was overthrown and 'killed', which then could easily have shaped Uncle into becoming the scared ruthless murder king he ended up being.
(I have to rewatch the doc sugarfoot ep to remember the timeline but I think Hector knows and remembers when doc was overthrown. Assuming he and Uncle are near the same age that means Uncle could have been a kid when the royal family was attacked. A formative life event Perhaps)
