Review Detail of Skyriano in The Greatest Disciple of the Evil Sect

I'm currently on Chapter 16, and so far the protagonist hasn't activated his brain, the "system" he has is guided by the typical dwarf demon who tries to annoy the protagonist instead of helping him with suggestions. In one chapter, he mentions feeling too impulsive for killing as if they were "NPCs," but two chapters later, he says "those NPC bastards." The dwarf demon needs to stop him from attacking a group of hunters, which would result in his death. This protagonist has more stupidity than villainy.
