As for being guided, he got the same instructions as Doria who managed to keep it together despite being scrutinised.
I agree that he has behaved like a complete tool, but equally I think it was strange that Harry and Meghan didn’t go and see him in person before the wedding. Wasn’t he supposed to be walking his daughter down the aisle, on TV in front of millions, in a country he doesn’t know and with the Royal Family present? That’s quite a big ask. He probably needed more instructions than Doria. It all seemed a bit haphazard and disorganised. That in no way excuses his bizarre and at times threatening behaviour, but it does seem to me he was set up to fail over the actual wedding 🤷♀️
