You honestly don't think Barb has been suffering from dementia for years? Is she faking what Chris talks about in the 7/25 letter? He says her body lives on and her mind is "zombie like".
Actually, I do think that Barb has dementia to some degree. However, I'm not sure how severe it is, and I also know that there currently isn't any real proof that she has dementia.
What I don't think is that Chris raped Barb as part of some power fantasy or to assert dominance.
To me, it's much more likely that in her demented state, Barb was sexually inappropriate (common symptom), and Chris assumed Barb was making a move on him (as he claimed to Bella initially). Chris hid it from the public and lied about it because he knew incest would get him in trouble (He has talked about his infatuation with his mother, and he has talked about how he knows incest is a crime). Is this rape due to dementia? Probably. Is Chris a sex crazed maniac looking for old ladies and little kids to fondle? No.
It's been a while since I felt sorry for Chris. The last time was probably the idea guys. Since then, he has been responsible for everything that has happened to him.
I don't see any connection between Chris having sex with Barb and sexual attraction of any kind. Barb is more of an object to him like his waifu pillows than she is a galpal. He used her and knew it was wrong and did it anyway. That isn't just overactive libido. He was exercising power over her. if it was just horniness, it would have happened much earlier, not when Barb is losing the ability to tell him no.
Yes, Chris is responsible for this, it doesn't matter if Barb consented or not, Chris decided to do the deed, so Chris is responsible for incest regardless of consent.
Just because you aren't sexually attracted to Barb doesn't mean that Chris isn't lmao. There is a well documented history of Chris being sexually attracted to Barb. Multiple dreams of sex with his mother. Dreams of Barb doing an Egyptian belly dance.
For a few months before the incest, Chris had been complaining to his friends about an uptick in his libido and how sexually frustrated he was. Why didn't it happen sooner? Chris was on HRT, he almost completely lost his sex drive and wasn't even able to get an erection for years. Presumably, he went off his meds around the time he started getting sexually frustrated.
