It is not about attraction. The goal is to terrorize and humiliate - to inflict as much damange on the person “needed” for the sociopath (rapist) to derive pleasure from the horrified, helplessness of the victim. It makes the sociopath feel all powerful - not a feeling he can get using his own (worthless) character or legitimate effort. Somtimes helplessness is key - the perps have a sexual desire to terrorize someone markedly helpless by physical debility or age. That’s why you get people raping the edlerly, infants, the mentally impaired.
Yeah, I’d imagine that does play in. I agree with your take on it.
By rights I’d love to see this old woman pull the switch on these two.
