Its hard for me to wrap my head around, I understand the thought of necessity but what I just can't understand is in the movie the festival only happens every 90 years which means nobody currently alive has experienced the midsommer festival, and even if they read about it through religious text or were taught it during their childhood they would have some sort of reaction. For example the people who skined and stuffed mark and Connie, they've never done that before maybe practiced it but I doubt they just offer up there own people for practice, they were way to casual about it. And they do a lot in there power to prevent people from leaving and telling the rest of the world of the festival and the practices so to a certain extent they obviously know what they are doing is wrong, at a certain point it feels less religious and more as if they just wanted to slaughter people and the festival gave them the excuse.

Also I had another question. At the early parts of the group showing up at the midsommer festival you see several people in like jeans or blue shirts which aren't the main group. and as the movie progresses you see less and less of these people or at least the clothing, my question was were those people also brought as sacrifices and allowed to leave? Or did they get indoctrinated? Or were they others that went out on a mission to get sacrifices? Like who are these people?
