His tone is matter-of-fact, but he is sincere with everyone and rarely ever raises his voice. Everyone thinks of him as a fine young man. However, that is the result of continuous training to behave like a human.

His sole purpose as a weapon is one thing: "To reliably stop the vital signs of any target he comes into contact with."
