Just saying: I never liked the concept of hell. Especially if it is governed by someone.
It's just so egotistical and silly -- that an entire realm would be generated, purely to host the souls of a particular race and "torment them for their sins", sins that are completely arbitrary and change with the times. And then you have this god of hell, whose entire life orbits around the idea to lord over a very particular group of humans.
It's kinda hard to write about this subject without being cringe, it's just such a shitty topic when you personify it. Even something like the grim-reaper is just total BS -- it's an entity which is in the eternal service of being the after-life chaperone to the oh-so-important folk of every ethnic group in the world.
I'd much rather have something like a Chaos god from Warhammer, which is quite literally the personification of a particular sentient-race's trait when distilled to an extreme, rather than have some being that only exists because humans need to be the center of the universe.
TLDR: More than not, "hell" is boring, having a 'god' whose entire reason to live is to obsess over humans is boring. This is my sleep-deprived, rambling way of saying: this arc is pretty dull.
