"Diana is only a few weeks older than me , she really needed a good friend, someone older, but then she rejected all good advice on how to cope with her life 🤷‍♀️ she did not seems to get wise, just more cunning, not the great parent that she is deemed to be, good parents don’t include kids in their drama" -

Imo she was far too young for the role, and was a victim of poor parenting herself. I agree that she made some VERY poor choices but imo she was fundamentally as thick as two short planks. An intelligent person would have run a mile from the whole Prince Charles thing. And a lot of girls did - including Camilla.

"they have the sociopath genes in the family and unfortunately the circumstances means that kids born with that tendency are indulged, like edward 8 and andrew and they become appalling criminal adults - and then the behaviours become so bad that they can’t be ignored and public drama ensues" -

I don't actually believe in sociopath genes - imo sociopathic behaviour is more to do with parenting and modelling from caregivers. Both the examples you give were raised by nannies - as was King Charles - and those nannies were more or less abusive. Particularly in the case of Ed8 - he was a profoundly damaged human being - bordering on mental illness - and had been from childhood. There was also a large contingent of the aristocracy who all shared a similar remote parenting regime - nannies etc. so the royals were not particularly unique. They were just more visible. And there were a LOT of people who cheered them on in their bad behaviour for a lot of different motives.

I do consider that the British royals have a fundamental streak of plain ordinary stupidity - you can see this from the Stuarts onwards, that is exacerbated by mostly remote parenting and unrealistic expectations from various governments/the general public. Small wonder that so many decided to resign from being reasonable human beings.
