Just hear me out ok?
Nyarlathotep, the often antagonistic and all-powerful character who employs complex tactics and elaborate plans to harm beings (mostly humans) who are supposedly minuscule in comparison to him.
Beyond cataloging these actions as truly "Good" or "evil" which we all know is not correct since human morality is completely irrelevant to these beings and blah blah blah, what is Nyarlathotep's reason for being this way?
More specifically: What's up with all the dark aesthetics, the contempt, the macabre aspect and the death threats? What's this guy's deal? He purposefully shapeshifts into "evil"-looking monsters and goes out of his way to act like a jerk, not just like a destructive force of nature but as a calculating troll. Is he actually an eldritch being with human like characteristics like sadism? Is he just bored? Can he be bored?
Of course, the obvious and correct answer that one may give is that, "His motives cannot be understood by the human mind, and or does not exist, he just IS" but let's dig a little into what these mean:
The previous answer implies that:
-Nyarlathotep does not really cause harm to others because he is bored, hates humanity, or has fun doing it, this would be attributing human aspects to him, which he lacks in it's true unfathomable form. If he is truly as unfathomable as any other outer god, we cannot say he does things because he is bored or sadistic or because of any mundane earthly motivation.
Which means that either:
1- Nyarlathotep is capable of having an extraterrestrial internal logic (let's call it eldritch logic) that we cannot understand in any way because we are humans. In this eldritch logic, the action A: "Not destroying humanity" (or doing something else or nothing at all), may be less desirable than action B: "Destroying and harming humanity" and he simply goes by this logic, or whatever it may be.
2- Nyarlathotep does not even have anything like an eldritch logic becauce he is a being beyond that imaginary concept, ergo, he has no reason at all to do what he does, if he carefully makes a plan to make humanity destroy itself in one hundred thousand years, we should be thankful he is being extra about it, because it has no reason to be this way and he could very well have destroyed the planet long ago, but did not for no reason at all, yet.
"So, what does this mean? And how does this relate to Nyar becoming our friend?"
Ok, well, i will be honest with you, no matter which of these two possibilities is used in a story in which Nyarlathotep appears, the realistic possibility of Nyarlathotep not killing or doing harm to humanity in universe is very very very very thin, but not impossible:
A: Nyarlathotep could change opinions or find a reason (inside it's eldritch logic) in favor of not harming humanity, that could result in him becoming friendly (yay), this is a speculation because we don't know how the hypotethical edritch logic works, but the possibility of it being changed could exist.
B: Nyarlathotep has no reason for destroying humanity whatsoever, so, at any given moment in the infinite cosmos, he could just stop doing it.
So, in conclusion, given that Nyarlathotep is not truly evil, nor he should truly be considered sadistic (given that sadism is a concept made by humans that could only apply to humans or beings of a three dimensional reality) there is a minuscule, minuscule, chance inside of the Mythos for him to be friendly at least once, in theory.
Like the title of the post says, sanity has completely left me, any correction on how Nyarlathotep works or discussion about my mad rambling is welcome.
