yea and they even said that all this misfortune BS including her need to even be a "spare" in the first place would all go away if they beat the misfortunes (if anything she should be helping them!). it really doesnt make sense...
let's just chalk it up to her being manipulated by the hand of fate! (aka plot convenience)

killing either or both of the boys wont stop the misfortunes. the "overseers" even mentioned before that no one has ever beat the misfortunes, which means they all ended up dying before they could win. that means even if one of the boys die the cycle will just repeat again later with some other descendants (possibly even hers).
this is why we are all confused and annoyed by her actions.
Wait. So you don't want to be a replacement of the misfortunes and by doing that you will kill the bois?
Bruh. I dunt follow. Won't the misfortunes STILL flow to you because they didn't beat the misfortunes? And your replacement hell will still continue because of that???
