Personality
Catherine is a rare example of a female sociopath in popular culture. A charismatic, seductive, manipulative, and narcissistic author and serial-killer. She manipulates and causes the deaths of nearly everyone in the story, including many of her lovers and her own parents, largely for her own personal gain, amusement and to inspire her novels with no real remorse whatsoever. She is even described as a "sociopath" by multiple characters in the films.

Despite the fact that Catherine is apparently a monster who enjoys killing people for the hell of it and likes to mess with the minds of others and exploit them for her personal gain, with her freely admitting she never truly loved Johnny Boz, she freaks out over Roxy's death and changes her mind about ending her relationship with Nick because she apparently decides she doesn't want to be without him, even though she is still secretly considering killing him just for it. There's also the possibility that she was scorned by Beth Garner and murdered her husband as a result.
