I wasn't a fan of hers and thought she should have been charged, but obviously it is very sad it lead to such a tragic outcome. I think some people think she was a victim of the hounding, not a victim for being arrested (well, that's how I felt anyway).
But some people are completely on PS side and think he can do no wrong while simultaneously vilifying her, as if every person that has had an issue with him are all lying because there isn't a police report.
The one thing we do know is even if he couldn't have gone to the police about his brother because he said he thought he was 16, it says a lot about someone that they wouldn't be disgusted with their sibling and concerned about that child. Surely in all his years talking about different issues on tv he has at least once discussed child protection or vulnerable teens or gone to related charity events? He can't plead ignorance
As for the NDA, if the runner was over 16 when/if something happened then no police report, but it would certainly tarnish his image if it got out because it is disgusting. Ok, we don't know what is being hidden but it is not outrageous to think this is the reason why he would want one, particularly after he didn't fall out with his brother when he found out about him until he was charged.
Anyway, as for BeKind I think it just makes people think can't speak up about bad behaviour.
There's a difference between being truly nasty and having an opinion on someone who's actions are wrong. EG 'don't like the person because I don't agree with x,y,z' compared to sending messages or posting public tweets threatening them or telling them they hope they die.
