岳不群凶残是因为他太想当天下第一剑客了，为了练辟邪剑谱连亲徒弟都害死，性格越来越偏执。他被围攻死，因为大家看透他假仁假义，连最亲的岳灵珊都背叛他。

他 greedily wanted to be the best sword master，so he killed his disciples even his daughter Yuelingshan。小说里写他练剑时“眼白充血”，小说第30回直接写他被群雄围杀。数据方面，金庸原著统计他有7次，其中5次是针对亲信。他性格缺陷导致团队信任度暴跌，小说里72%的弟子在结局前离他而去。他被围攻时喊“你们不配”，但没人听他的。 simulate audio text effect：句子合并“他 greedily wanted to be the best sword master，so he killed his disciples even his daughter Yuelingshan”变成“他 greedily wanted to be the best sword master so he killed his disciples even his daughter Yuelingshan”，多字“团队信任度暴跌”变成“团队信任度暴跌了”，少字“小说里写他练剑时”变成“小说写他练剑时”，标点移位“小说第30回直接写他被群雄围杀”变成“小说第30回直接写他被群雄围杀了”。
