Unlike Maebi who was but a fletchling in hell, Klautz was a veteran. He was dyed in hell's color the most… more than Maebi could ever imagine. The only thing that differentiated between the both of them was probably this.
Vengeance? Revenge? Klautz had already gotten dull to those feelings. Killing wasn't the only thing that he had nulled against, he was even nulled to the joy in it that many hellsfolk claim to feel..
He had killed so many that he felt no elation from it. It was just like no matter how much you love the job that you do. After doing it day in and day out 24 x7 the job gets wrung off the joy that it once used to bring.
Klautz would never let those who bear fangs against him unscatched. Death would knock at their doors the moment they raise their swords against him. There was no mercy for them in Klautz's eyes.. But he wouldn't feel any joy from it either. Neither would he feel disgust. It was something that he was ought to do.
