At this chapter ... Finally i realized, MC is living in a fked world, consisted of fked society, bonded by fked values, enforced by fked governance, & lead/influenced by fked individuals.
So... Please refrain yourself from using our normal daily life values as viewpoint and judging standard for this manga, just read this as 'inverse version' of our world
@collagen
At this point ... Isn't that just a title/nickname given by this kingdom to some random dude to "do something", cz that random dude is dangerous/un-controlable to them.
I wouldn't be surprised if MC got the title of 'Demon King' next.
