Its not surprising really.

Public and private lives are very different.

I bet most child sex offenders or any sex offenders when caught surprise people who know them.
Add in Hollywood people being idolised to almost god status and the entitlement takes over.
We had Robert Hughes who was allowed to continue his ways because the show made money

He was politely asked to leave the show because it became an open secret and they didn’t want the wholesome image of the show to be affected. The scandal only came out when Brisbane radio hosts decided to do an on-air reunion and all the cast said. “we won’t do it if Robert Hughes is there”, prompting an informal investigation. I believe, but could be wrong, that it was Simone Buchanan who originally made the allegations. They kept quiet to protect Sarah Monaghan, who played Jenny.
