Yeung Hong's death must have been an emotional roller coaster for Gwok Jing. On the one hand, a dangerous enemy who had murdered Gwok Jing's teachers was dead. On the other hand, Yeung Hong *was* Gwok Jing's sworn brother.
What was Gwok Jing's overall disposition towards Yeung Hong's death? Was he relieved/gratified that his enemy was dead, or did he mourn the loss of a brother?
Gwok Jing's disposition towards Yeung Gor during ROCH leads me to believe that Gwok Jing was more saddened than gladdened by Yeung Hong's death.
