once they transform into a demon, they all would be corrupted by muzan cells to not think straight and only search something to eat no matter the purpose, once they demons they get their most violent side out so it's no surprise this was gonna happen.
Imma go out on a limb her and say: Muzan problably made Tanjiro seem more lie a demon to the other by increasing his demonic aura or smth like that and maybe thats why Nezuko attacked him bc as we all know her eyes get slit pupiled when she fights or senses demons. So when Tanjiro felt that his friends (and mostly sister) abandoned him, thats when he trasformed, got corrupeted or whatever. and so thats why they turned on him even tho he saved rengoku
Can I say one thing not that I’m hating but how tanjiro became so strong is cuz muzan gave all of his blood to tanjiro to create the perfect demon but I don’t mind this
truth be told this is false, it doesnt matter how much blood one recieves at the beginning, unless there a swordsman, and the sun breathers take all of his blood to become a demon, so the truth is its literally his compatibility, tanjiro is so compatible with muzans blood that he surpasses muzan himself.
Okay so let's just have the best time in our life bc we're gonna die like R.I.P it was nice to know the Hashira we all finna go to heaven together if there working together like there's no escape 💀
