Zhi was a man who felt horribly belittled by life & family in general. The pressures of being fired, his wife divorcing and leaving him for a refrigerator salesman and the constant disrespect from his own children caused Zhi to accumulate pent-up rage. He sees the outbreak as time to spend on his own to groom his Zen Garden and for some "peace and quiet" He wields a Guan Dao, and uses it to decapitate all who disrupt his peace.
