The chapters describing Cathy as a child & teenager repeatedly show her "seducing" older men. At least one of these is described as looking like assault.
The evil Cathy is coded as asexual, and asexuality is conflated with inhumanity and abnormality. Quote: "without [sexuality] one would not be a human. One would be a monster." “everyone, I guess, who is not abnormal has foregathered with little girls in some dim leafy place, in the bottom of a manger, under a willow, in a culvert under a road—or at least has dreamed of doing so”
