I don't think he did. SteveThomas points out many times in his book how that poor child was manipulated. He mentions e. g. one episode when JonBenet felt cold in a restaurant where the family had gone after the pageant, and Patsy did not allow her to put on a jacket, telling her "You're still on show".tipper said:He thought she had had a great childhood.
On the last page of his book, Steve Thomas thinks about what JonBenet could have been, but what she was never allowed to be: a child having a real childhood.
And he was of the opinion that JB would eventually have rejected the plastic Barbie doll lifestyle later.
I have the impression that Steve cared more about the victim JonBenet than her parents did.
