@Akemua but satowa's mom isn't much different from her or hiro. she also had a 'crappy past and trauma'. she was just an ordinary loving mom until her husband died and she was forced to assume responsibility for the houzuki clan, when she was a nobody, with no talent to speak of. she was desperate and under enormous pressure
i even think what she was doing up until she excommunicated satowa was fairly tame. i don't think it's really that awful for a parent to overrule and decide everything unilaterally for their child, especially when there's so much riding on her
i mentioned differing cultures because of this. you might think it's ridiculous to ignore a child's wants and treat them coldly and harshly to further a group's prestige and success. but from a collectivist mindset, the group's success might be much more important than one kid's happiness. in that context, to rebel against and sabotage the group's name, just because you want to cry out for a little bit of empathy seems more ridiculous than kicking said rebel out
and about west vs east, i mentioned it because it's more often the case that a western culture values individualism more than collectivism
i think you're being a bit too harsh on satowa's mom. she really did want to say sorry and reconcile. but a) she felt that what she did was too unforgivable to try for an apology and reconciliation and b) satowa was a black mark on the houzuki name. even at the revitalisation concert, there were people who opposed her return. it's not as easy as giving the middle finger to those people and doing whatever you want, because she has a responsibility as the head of the clan
ultimately, i think satowa's mom is a more sympathetic character than you give her credit for. we saw that she was a pretty loving mom before becoming the houzuki head. she just couldn't do the right thing when faced with heavy pressure and expectations. and she also realised that what she did was wrong, on her own. i think that alone speaks volumes about whether she's a good or bad person at the core
