On This Is Us, Jack's family is his whole world, and he takes pride in raising his children well and keeping his wife happy. He is shown as a compassionate, loving dad, who would give everything he had for the people he loved. (He told the doctor treating him post-fire that he saved Kate's dog because he "loved the girl who loved the dog." Ultimately, he died because of it.) Never snarky or cruel, Jack was revered because he loved deeply and honestly. He set an enormously high bar for his children, not because he had some intense career or achieved some great external accomplishment, but because he was good. Kind.
