JR is a truly awful person, and it's a mark of his terrible personality that when he was shot in Dallas's shocking season finale cliffhanger, the question wasn't, "Why is someone shooting JR?", it's "Who shot JR?" Because there were so many people who had a perfectly reasonable motive to kill JR, it's hard to narrow it down. Basically anyone who interacted with him could have been expected to want him dead. He's a terrible husband, with loads of mistresses and casual affairs, and he's certainly not much better as a father. His ruthless pursuit of money and power as an oil baron made him a man with more enemies than most people have Facebook friends. Nonetheless, he quickly became a popular character, and the show that was originally supposed to be an ensemble piece about two feuding families ended up with a laser focus on JR. All thanks to Larry Hagman's thoroughly nasty portrayal of television's greatest psychopathic one percenter.
