Sorry, it's a part of her story, too... I think we cannot forget what really happened to her. I know most of the people are more interested in guessing if yes or no with Fersen. Maybe you are ?
But this terrible dead, and the way she was left for days on the ground, definititely belongs to her fate.
There's nothing morbid about that. Just, in my view, an expression of the fact that we don't only love a glamorous queen. But Marie-Antoinette, with all her sufferings and misfortunes.
