I really like this take. I did get the impression that Dax is also kinda the wild child of the symbiotes too, for many of the reasons you listed. They are also very passionate about their friends. They chose to uphold a blood oath that even the Klingons didn’t consider binding, they stood by Sisko for 3 lifetimes, they refused to break the confidence of one of Curzon’s married lovers, at the risk of their life, and they protected Jake’s book, for many centuries. They hold onto these generational bonds, even though its taboo for the Trill.
