YMMV / The Iron Buddha

• Complete Monster: Xiao Tianzun is a vile Serial Rapist and mass-murdering criminal who begins as a particularly nasty kung-fu disciple stopped in the middle of an Attempted Rape. Shown lenience by kung-fu master Liu Peng, Xiao Tianzun repays mercy with treachery, first exterminating his entire clan before moving onto Liu Peng. Xiao Tianzun has his way with Liu Peng's daughters while forcing Liu Peng to watch, murders the three of them, then goes on to kill all Liu Peng's students with a poisoned sword meant to kill them as slowly and painfully as possible. Xiao Tianzun even slaughters an entire family and all of his own co-conspirators in his efforts to trick the hero, culminating as he impales the hero's Love Interest out of spite.
• Moral Event Horizon: Xiao Tianzun killing his mentor's entire family proves that he is beyond any form of redemption. At all.
