I think we can all agree that Bojack, as the main character, beats many if not all the main cast when we talk about being morally corrupted. Still, who have you considered a " worse person " — the definition of bad person isn’t really precise I know, but consider it as " person who does actions generally considered deplorable by the public. " — than Bojack while you were watching the show?
Princess Carolyn. Her whole job is to cover for Bojack and other Horrible Celebrities then proceeds to justify it for herself. From going one scene in us feeling sad for her, to us watching her destroy someone’s career or pick them apart. She does it so casually, callously, and continues to go forward happy, only worried about the main cast -> namely Bojack & Herself
