Strictly speaking, this was my first time committing murder.
However, perhaps because I had done many things akin to murder in the past, or because the person I killed was truly deserving of death, I felt absolutely nothing about it.
Or maybe, as Agent Kong had indeed said, killing was just too easy for me—a mere flicker of thought could reduce someone to ashes. There was no bloodshed to see, no screams to hear, just a flash of fire, and the person I killed might not have even had the time to feel the agony of death. Therefore, as the killer, I couldn't feel any sense of reality, let alone guilt.
I didn't consider it a bad thing. I might very well continue fighting with others in the future, and it was likely I would encounter situations where I must kill again. It was much better to remain unfazed than to develop a resistance or an unnecessary fascination.
