Since the beginning of the battle, the devil worshipper believed that the situation would develop just as he anticipated. The angel would be surrounded; the mercenaries would split up their force. According to his plans, Rhode would have to step in to either help his men or the angel.
The angel, despite her not being a high-ranked among angels, to the common men, she was recognized as a divine being. He didn't believe that the human noble would leave the angel to die alone; not to mention that she was a beauty as well.
Thus, the devil worshipper attempted to split Rhode and the angel when he situated his undead in two different ambush areas.
