The typical wuxia villain is motivated by lust for power. They pursue great martial arts, wealth, or political influence so that they can have power to bend others to their will. Typically, this is done by using a combination of brute force and deceit to kill or intimidate their enemies.
Seung Gwoon Gum Hung of Gu Long's SENTIMENTAL SWORDSMAN, RUTHLESS SWORD has power aplenty. In his wulin, no one can truly threaten his power (not even Lee Chum Foon). Unlike most wuxia villains, Seung Gwoon Gum Hung rarely directly used his martial arts to enforce his will upon others. Instead, Seung Gwoon Gum Hung seemed to enjoy playing mind games against his enemies. Ah Fei, Lam Sin Yee, Ging Mo Meng, Lung Siu Wan - during SSRS, we saw Seung Gwoon Gum Hung play psychological games against all of them at various times. Seung Gwoon Gum Hung's martial arts were so powerful that he could have killed any of these people through physical force quite easily, but he preferred to not kill any of them...instead playing mind games with them that intimidated them and weakened their willpower and planted self-doubt in their minds without any overt threat of physical force.
The thing is, Seung Gwoon Gum Hung seemed to enjoy playing these mindgames more than anything. It's not that wealth and power meant nothing to him; he had accumulated plenty of these goods, but he seemed to be driven more by being able to psychologically dominate his opponents than anything. Wealth and martial arts seemed to only be tools through which he achieved psychological domination of his enemies, and he seemed to achieve more through clever and canny emotional manipulation and intimidation than through his powerful martial arts.
No other wuxia villain that I'm aware of does this...at least not as elegantly as Seung Gwoon Gum Hung. He's a villain, and he's evil, but there's a twisted nobility about him that you almost have to admire.
