There are a lot of tsundere out there, some more violent than others (and a few not really violent at all - this discussion only concerns the genuinely abusive ones). Few of them are really justified in their bitchy violence, but some of them could at least be forgiven, if they'd stop the violence, sincerely apologise, and try to make up for it (and in many cases, get a competent therapist). Others, however, are so cruel, that no amount of grovelling could make up for it. Jail time and/or slavery might, though.
In all of anime, manga and related games, who would you say is the least forgivable tsundere?
IMHO, Louise Franþoise de la Baume le Blanc de la ValliÞre, aka 'Zero', is certainly competitive: even though its played for (disturbing) laughs, and the injuries heal right after, it clearly still hurts to get them. Tendo Akane and Narusegawa Naru are quite a bit less sadistic to their male leads, which says a lot.
