Possible alternative theory for the ending?(Spoilers)
What if Pelle was controlling and manipulating Dani the entire movie. What if Dani was actually the one suffering from mental illness(which is why she was tripping out while on psychedelics) and Pelle knew this from his talks with Christian and decided to exploit that to alienate her from all her loved ones so he could have her to himself in the cult. This could be why she kept having flashbacks of things she wasn't even there for/seeing her parents and kept feeling a sense of guilt(that she had killed her parents and sister)
What if he convinced her to kill her own family and eventually kill Christian by playing to her fears that no one around her was "her home" except for him and his cult? He did draw her as the May Queen long before the competition and kept talking about how excited and happy he was that she was coming.

There is some truth to Pelle grooming her to be May Queen. He basically says it to her before they leave and the other women were obviously purposely losing the dancing game to make her be May Queen.
What’s certain is that the cult/family(?) had clear plans for each of the outsiders
That was a theme that kinda reminded me of hereditary. They showed up to the festival naively thinking that they had a choice of how much they can partake in the rituals and festivities but in actuality, their fate was already sealed.
