I think both Charles and Diana were victims of societal and, particularly, royalty expectation. Yes what he did was bad but he was prohibited from marrying Camilla and was forced into marriage of conveniences. . I honestly don’t see him as spoiled brat. He and Camilla were forced to be apart but at the end love prevailed. They suffered for nothing (except that of course they had William and Harry). Charles, Diana, Camilla. Monarchy is a cruel thing. It didn’t need to be that way
