Killing goblins was not an easy task for anyone. The hunter association knew that the first kill was always traumatic. It wasn't an easy task for a human being to murder someone so mercilessly. Hence, one of the first traits the ones investigating and grading the participants look for are the ones who could stomach the kill. That is one of the prime requirements when searching for a suitable hunter.
Yet the scene in front of them was enough to shock them. To their surprise, not only did they manage to spot someone who could stomach the whole thing, but that someone was able to do so without even a slight change of expression or emotion. He was clearing through the monster mob as if they were chickens in the path of their slaughterer. There wasn't a single ounce of regret or hesitation when he did that, and neither was it difficult for him to kill them.
