I wonder if there is an element of self-denial (not with Jimmy Savile, as he proved to be cocky and arrogant in how he deceived the public). Personally, I think that RH probably loved his wife in as limited a way as he could, perhaps putting her on a pedestal, and loved his daughter in a normal father/daughter way, although I think she may have had suspicions about him. Was this a deliberate smokescreen, or a 'split personality', separating his jolly persona and portrayal of happy family man from his other, darker, character. Or was it all a deliberate pretence?
Of course, being imprisoned awaiting sentencing has not always prevented suicide. Some would say 'good riddance' but others would feel they should have faced justice and served their sentence.
It sounds as if he had a rather strange upbringing, but it leaves one wondering about the nature or nurture conundrum.
