Their parents told them to be nice to Hari but all they did is to bully her for a long time in the original timeline.
Thankfully the eldest has some sense (maybe because he got beaten?) and guilt.
Eugene is just barely redeemable. He KNEW that putting all the blame on hari was wrong. He KNEW that hari being there was making their mother well and happy. But he STILL participated in and covered for the bullying the other two did? :|
Cabel is barely passing but erich almost killed her
