>Noble Faction is trying to acquire power to kill him and Tomboy Princess
>5 people he hunts this chapter have a connection to said Noble Faction
>He kills them preemptively to quash a potential future problem in a way that will NEVER be attributed to him
The people questioning why he did this are joking right? He gets new skills, removes future enemies for him & Tomboy Princess, cripples the Noble Faction(again), and will never have suspicion cast his way. It was a brilliant plan executed to perfection. How you can read 63 chapters of this manga and think this is out of character or "too evil" of him should probably reread it from the start.
