Eh? Seriously? After being screwed over, insulted, and humiliated like that she still considers them family and willingly goes through with the whole sacrifice bullshit? How pathetic. Kill yourself to get back at them. It'll ruin the standing of the family and one of the girls that helped keep her down will then be "betrayed" by that girl, too, and be thrown into the sacrifice position which will destroy any trust she may have built with the rest of them. Sure, the family won't collapse, but it'll greatly weaken them and I bet that sack of shit "father" will take out his anger on the older sister. Revenge all around. But no, she's just doing what they tell her to like a good little puppy, wagging her tail as they tie her up to a tree in the middle of nowhere and drive off.
