So, they let him escape who knows how long ago, and now they're shocked, that he's doing this? Are they idiots, or are they idiots? Should've killed him a gazillion chapters ago. And I'm worried, that this moron of an MC is not going to kill him now, either... And that it'll lead to this Dex causing more and more trouble in the future...
I really hope I'm wrong and this MC grows up and rids himself of his idiotic "old world morality", or, in case I'm right, Dex kills him so we don't have to suffer the idiocy of this MC any further.
