It is sickening, assuming it is true (and I believe it is) that he had sex with a girl only a couple of years older than his own teenage daughters at the time.
There was a really well-written article a few weeks ago in the guardian where the author said fir men like PA and Epstein, there were two types of girls in the world, girls which men like them could do what they wanted with and girls who should be protected from men like them at all costs (like Beatrice and Eugenie).
I'm not sure what crime you can convict PA of, as she was over age and I doubt he was personally involved in trafficking, unless she didn't consent to sex and he raped her.
But this is the complexity of trafficking, she may not have technically been coerced at the time and may have looked like a willing participant, but she was obviously pressured, and put in a situation she didn't know how to get out of.
I think we can all remember our 17 year old selves and think about how we would have felt in that situation, with an actual member of the royal family.
As for PA, I'm sure they'll just weather the storm and hope it will blow over. But I certainly think he should just quietly bow out of public life and crawl under a rock somewhere. I don't want to see him at the patron of charities or on the balcony / in carriages at Royal events.
