I have no doubt. He is sick!!! I have so many questions but I know we’ll never get answers. This display of behavior is beyond sickening. It seems as though every time a picture/video like this is displayed, parents are silent or do/say nothing. Something is going on we don’t know about.
Is Jill that naive? My guess is she can’t/won’t deal with it.
My experience with this is that in general, the wives do know, but they trap themselves in denial about their husbands’ perversions and sicknesses. Even more so when their husbands are associated with power. Jill almost certainly knows Joe is very very sick and dangerous, sadly she’s deluded herself completely about it and tries to deny it away. Psychologists have a term for it and now sure what it is, but it’s clearly some sort of cognitive dissonance.
