I very much doubt that any man, even most Psychopaths can commit rape or paedophilia "to order", for financial gain, Tim. I'm sorry to blow your theory out of the water here, but I have never heard of this kind of psychopathology.
The motive for rape was sexual aggression, fantasy, coercion / control.
The videos of the rape and paedophilia were just a sideline for him to make money.
ie: his twisted deviant sexual pathology is present already - the realisation that money could be made from that came after.
hopefully it will all come out soon. - we know for a fact that people do traffick for order so ill let that stand.
part of the discussion here though is to just throw out there theories that fit the bill. None are right and most are not 'impossible'.
many narratives fit actually. we should entertain each and keep an open mind and base our understanding on what we know. Not so much on what we think.
