Why is Jolee's backstory not discussed more?

He literally left the Jedi, not because they were cruel to him, but rather BECAUSE THEY FORGAVE HIM for not killing his wife (who fell to the dark side) when he had the chance. Like how is that not discussed more? That's a crazy plot point that I think is super unique in media in general. Like the Jedi forgave him but he didn't forgive himself and THAT'S what made him disillusioned with the Jedi. What a deep and unique message about the difficulty of self-forgiveness in a silly little Star Wars game
