Traitor

"Don't worry. I do not mean that I want to kill you as well. All I am saying is that my ability to kill is being restricted by the Blood God above me. With him gone, I can freely kill anyone I want," he said. 

"How has the Blood God impacted your ability to kill at all? You are his most trusted person and he will give you anything you want," the Fire King said.

"I didn't think I needed to explain how the Blood Element works to you. With each person we kill, we hone our elemental power. Why wouldn't he be stopping me from killing too much? Every time he stops me and kills people for himself. He deprives me of that pleasure and also stifles my growth, giving me just enough to stay strong and useful."

As he said that, he judged the reactions of the people around him. This was the only way that the plan would work - depict himself as a psychotic person being bounded by the Blood God. It was clearly working.
