He should be caring and kind, yet nothing he does matters in the long run.
But what he does do matter in the long run, the reason he's forced to repeat the whole thing is because he doesn't really care about anyone except himself. If it really didn't matter there would be no consequences, but there are. The world may not feel "as real as before" but it doesn't change what he has to do.
They keep telling him to be a better person, yet the rules set in place does not incentivise being a good person.
The fact that the rule "only killers get exp" doesn't apply only to the hero is veery strange, I agree. It makes very little sense.
Even if he does one day 'learn' and pass the test, it'll only be a facade. They aren't teaching him to be a better person; they're teaching him how to better hide being a bad person. It's like testing someone in art, after only teaching them math.
If they can't see behind his facade, considering that his only punishment is a time reset, I can only agree.
That does not sound like something good 'gods' would do, to me.
Lawful Good doesn't mean that you're going to be the good guy for everyone or that you'll not be an asshole from someone else's perspective, this is one example of that.
It's true that their system is in place because it favors the many, not our mc in this case, sadly for him.
He's not right, but he has every right to rebel against the shitty situation he was forced into.
Considering their powers, it's pointless. In fact, he's not really rebelling against the Gods, he's just speedrunning (and he's doing it badly because he doesn't understand the conditions for "winning the game").
My point is, and neither of us will probably ever understand this since I assume we're not psychopaths, MC prefers being a free psychopath over being a gentle tool. It's what every single step of the story keeps telling us, so I'm just irritated that people try to rage against it. Enjoy the story, or don't. Just don't try to change it; it's the author's story, not ours.
I agree, on the other hand I'm annoyed by readers who think the mc is "right" when the fact that he's "trash" is in the damn title.
Of course I'm not referring to you (I think it was pretty clear but you never know).
