First Evil Pandaren NPC?

Now that the Pandaren have been exposed to the Horde and the Alliance; I wonder who will be the first Pandaren NPC to turn evil and betray the Pandaren. It would make a great villain to fight and a great story arc/development to the new race. I got the idea after completing the Weapons of the Thunder King quest line in the Vale of the Eternal Blossoms. This quest line is opened up after you earned Revered reputation with The Golden Lotus.

How bad would it suck to have Zhi the Harmonious (Caretaker of the Thunder King's weapons) use the artifacts (Helm, Axe, and Spear) and turn them against the Pandaren?
