Nah MC became Sadistic. He always thought he was the best and was tormenting his victims slowly instead of a fast kill.
Jashm:why would he kill her? she is not a threat and her martial spirit is of his interest, besides he might want to use her and the ohters to train his clan members To kill every enemy is only necessary when the mc is too weak or needs to be low-key, with his flame and methods he doesn't need to act like that.
