His upbringing and success is like Zuko's. They both got brought down by negativity, hate and humiliation. They both used that anger and despair and turn it around but let themselves feed in that. To never move on, to always be angry. To never let go. Jaek is successful monetarily, yes, but in mind? He is still a hopeless child who's afraid to lose and does not know how to channel their emotions. No closure, no empathy, only moved and pushed by anger!
