This goes in pair. You praise someone for the choices they make, it doesn’t make sense if it wasn’t a choice at all in the first place.
I think she was a brilliant and intelligent person, she proved it in so many occasions, and she didn’t become Queen or stayed for so long just because of social pressure and “daddy told me to”. So yes, I’m assuming it was a net positive for her, and that she dedicated her life to something she wanted to do.
Sure there are many shitty parts coming with the throne and the toxicity surrounding the whole royalty system, but I give be the benefit of the doubt on having done the right choices in her life.
