Revenge is a tried and true trope of wuxia fiction. It seems like half of all wuxia tales are revenge stories.
The three protagonists of THE CONDOR HEROES TRILOGY seem to reflect an evolving attitude towards revenge. Gwok Jing pursued revenge against Prince Yeun Nan Hung Lit of the Jin Empire and finally got it at great cost (the loss of many innocent lives) that GJ deeply regretted. Yeung Gor pursued revenge against the Gwok Family thinking they murdered his father and cutting off his arm, but changed is mind at the last moment and decided to forego revenge. Cheung Mo Gei's parents committed suicide due to the pressure from wulin leaders to reveal the whereabouts of Golden Furred Lion King Tse Tsun, but never desired revenge against those leaders.
