@Z0mbieJr tbh I don't mind this flash back a number of people would react like this similar to the village people at first people didn't want that arc cause the hero got side track but after a few chapters finding out what kind of shit the villagers did and when the killing happen it's a lot more satisfying.
kinda like there's a difference between the amount of fun when the hero just kill the saint next chapter vs finding out she's some sick fuck idk maybe she's a pedo ass fucking kids or something and then killing her in a way related to her being a pedo. tbh the LN is far more detailed compared to the manga so if you want to get made at this sick fucks longer at read them suffer longer read the LN I guess.
