In the thread regarding Yeung Gor's premature withdrawal from the martial world, the matter of Gwok Jing's involvement in the Mongol invasion of the Central Asian city of Samarkand during LOCH came up. In both history as well as the LOCH storyline, this was one of the Mongols' most brutal campaigns, ending in a mass slaughter of the city's residents (not the first nor the last time the Mongols would do such a thing, but one of the most memorable times).
Does Gwok Jing's involvement in this incident color your perception of him? Gwok Jing was undoubtedly a noble man with a kind heart, and he did not order or condone the mass slaughter that Genghis and the Mongols engaged in at Samarkand (in fact, he pleaded in vain for the Khan to show mercy towards the Samarkandians), but there does seem to be a matter of at least unwitting complicity here (Gwok Jing, after all, was one of the Mongol Empire's chief military commanders at the time, and was an active leader in the war against the Jin Empire and their Mohammedian allies at Samarkand).
