honestly instead of the end of bloodline feeling like another anti - violence lecture even though devil was beating the crap outta someone who literally just abused and killed jin, i think they should've really played into the horror aspect. instead of them being like "JIN STAPH!!! JIN NO... JIN ENOUGH!!! JIN THIS ISN'T YOU... :'( JIN YOU'VE BECOME A MONSTERRR..." like seriously. realistically if your friend was literally SHOT AND KILLED IN FRONT OF YOU, then they rose up with a demonic appearance - you'd probably even question if that thing is your friend anymore. i mean, it's probably a similar experience to watching your friend become a zombie. hell, watching your best friend getting KILLED is probably a traumatic experience to begin with, yet... they can still comprehend everything enough to tell jin (devil, a very devilish looking guy now) to stop beating up heihachi lol

like i feel xiaoyu should've been horrified, maybe the others too. considering they've likely never seen a devil - and they certainly never seen somebody reanimated after being killed. the whole situation should've had them screaming, not just slightly upset. hell, iirc, when jin was first shot, xiaoyu just sounded kinda mad at heihachi rather than being absolutely devastated. like yeah, she screamed a little at first. but she was really,,, sobbing or anything. like "you're... you're the evil one" sounded like she had more anger in her instead of, like i said - being absolutely devastated. like she only started crying after devil started beating on poor heihachi.
