First off, I appreciate both of you actually responding with your own views and engaging me in a proper conversation with your reasonings for said views. This is more then can be said for some people.
But, I see this belief that the Seven aren't just blatantly apathetic to the greater suffering of mortal plebeians, and I have to offer my own counterpoint here. I'm going to write a lot here, but that's more because I get overly excited in these debates rather then me trying to drown the opposition in word walls or anything, so apologies in advance.
Not malicious, non-interventionist, there are conclusions that are easy to come to when looking at surface level. The surface level being their own mouths and the people deceived into worship them in-universe. And probably writers posting on here, but Word of God only accounts for so much if actions in-universe are running in opposition of it.
The Seven say they learned empathy from eating mortal souls? Snake also heavily implies that at least some of them believe that there's no afterlife, or that if your souls(or Ki, or both, it's some spiritual aspect that they do not specify which) gets screwed with enough it dissipates and you are gone after death.
If the former is the case, then the Seven are horrible for condoning the fates worse then death mortal beings inflict on eachother already in the absence of wraiths and demons. Slavery, rape, mindrape/killing, combinations of the three, with good ol' fashion robbery and murder on the side. That's all from places that follow the words and faiths of specific members of the Seven.
I mean, you can literally stumble into the Kitsune den because they left the front door wide open, nicely ask some friends you made about the bag Evergreen is paying you to find, and instead of telling you to get the hell out with an actual option to leave, they decide to beat you into submission, drag you to their leader, who can then proceed to forcefully genderbend you into a foxmorph that is then possessed by said leader, and whilst you are still consciously watching all this, forced to physically feel it and sobbing whilst trapped within your own mind, this leader uses your body to have sex(and rape you by extension) with someone else, all whilst the magical alterations of said body slowly mentally gaslight your consciousness into a compliant a breeding slave. Said leader then leaves your body, has a laugh at your expense whilst you're now physically sobbing, and then the mind alterations mostly takeover and that's that for you, the person you are has more or less been mentally killed in a superbly fucked up, drawn out fashion.
Now as much as I can appreciate some dark shit, you might be wondering why I am using this time to rant about Komari rather then any of the Seven like I had started off with. Well now, who is essentially omniscient in the affairs of the Kitsune den? With frequent physical visits, and indisputable power and authority?
Why, one of the Seven. Keros knows this has happened, he likely knew about it as it was happening, and he let that slide. Even if one does not want to interfere with the world trying to fight off an extra dimensional invasion of corruptive monsters for whatever reasoning, they have all the say in how their followers conduct themselves, they can tell them what is right and wrong. Keros himself has the ability to unfuck your body and brain in this situation, but he's apparently cool with this.
How about Mallach? You know what he never does after you build him his temple? Says "You know what champion, you've been doing a real good job fighting for the good of the world here and I appreciate that." Maybe he could not find the time to visit you before for reasons, the gods are so busy after all, but whilst you're there, you think he would at least express approval that you're showing the strength these shitheads are apparently looking for in their non-interventionist approach instead of just going on and on about how cool it is that you built him a temple and how it hopefully won't piss off Lumia, but wouldn't that be funny?
Lumia and Snek are a bit less blatantly sociopathic, at least Lumia acts outwardly kind, but all of this is a bit farfetched for beings that are supposedly empathetic for all the souls being corrupted, tortured and warped by the funni never ending hedonism legions. Mallach is at a party, one you find Snek hanging out at, whilst Keros is apparently perpetually on call to either fuck people that stop by his shrine or wreck someone's home life.
If they do believe that they should not intervene so mortals learn to be strong on their own, they should just be a b i t more regretful about the whole thing, and even then you'd think they'd be sympathetic to people getting soul fucked given how truly awful Lumia and I think(my short term memory is a bit spotty at times) Snek say they are about doing it to people themselves.
The Seven aren't bad because they're wraiths. They apparently gained proper emotions, after all. I've written eldritch abominations that have gained sympathy for poor 3 dimension meat beings, but have trouble expressing that or even understanding it themselves due to being partially incomprehensible greater beings. These ones are written far too human for them to not be reasonably held accountable.
They're bad because nothing they do actually aligns with any possible avenue for them actually being benevolent in any reasonable way, shape or form. They're too human in how they act and are written to reasonably be held to Blue and Orange morality, so that's not an option either. Lumia is the only one we've met with any reasonably redeeming qualities of any sort, and she's still complacent in the same negligence that all are damnable for.
Just wanted to focus on the seven morality topic here rather then the grimdark thing as a whole, because I'm slightly afraid I'd end up writing a short novel of ramblings then. One topic at a time for everyone's sake.
