A question for connoisseurs of lore. (Dark Souls)

Mushroom Elizabeth, in the "Prepare to die" add-on, said, it seems that there is not a bit of darkness in Artorias and undoubtedly the abyss will swallow him too, this suggests that on the contrary, in order to defeat the abyss, you must be dark and she also says that the abyss may not be stopped at all.
Judging by the lore and some of my thoughts, people can exist only in the balance of light and darkness. For when the flame goes out, apparently, the light is not enough and black souls are torn from people, and soon everyone will become hollow.
The arrival of darkness means the arrival of the era of people, even Manus in the game is called the first person, and fire is the era of the gods, Gwin and others, supported by bonfires, so it is unlikely that balance contributes to the existence of people, rather, on the contrary, it contributes to the existence of "cyclicality" if possible so to speak, we kindle a flame and prolong the existence of the fire for a while, but it goes out again and it is necessary to kindle the flame again.

So why do more and more people become hollow during this coming of darkness? So soon there will be no more of them. It should be the other way around. If Artorias was not hollow, then who was it? Even the gods were more human than Gwin before that and had a particle of a black soul in them. Which later led, for example, to the fact that everyone left Gwin.

In the second part in the trailer, we are shown how a knight dies in the forest, and later resurrects with a black mark and it is said that such people are drawn to one place fenced off from others, on the lands of Lordran, Dranglik, overlords in general, it is important that the mark appears on dead people, and not among the living, that is, people will not disappear anywhere, and the dead are pulled into the lands of the overlords, as I wrote above, apparently in order to fulfill their purpose or become hollow and die by the hand of the same bearer of the mark, this is a cycle to maintain the flame , the flame gives power to overlords. If the flame goes out, darkness will come where the masters will no longer be, people will rule, it is not for nothing that it is said that the era of darkness is the era of people.
If Artorias was not hollow, then who was it?
Of course, he was not hollow, perhaps a demigod by some or still a person, but unusual, after all, all four of Gwin's knights were not ordinary, maybe this is the influence of a great soul. And at the time of the fight with him, he was already absorbed by the abyss and by the way there are game files with his voice, that is, he had to speak during the fight with us, which means that he was still partially conscious, considering that it was he says, but the files were cut and you can find them on YouTube.
Even the gods were more human than Gwin before that and had a particle of a black soul in them. Which later led, for example, to the fact that everyone left Gwin.
And forgive me this complete nonsense, I’m even wondering where you read this.

They were human when they found 3 souls. This means that there was darkness in them, like in any other person. Although they may have been completely purified when they received souls. And then Artorias was really clean. And you're right.
One more thing, if really living people do not become hollow, but only after death, then it still sucks. For in the era of darkness after dying, they are doomed to endless suffering in the form of hollow). And can you imagine how many of them there will be over time? And what will happen after extinguishing the flame? They can then pounce on people and kill them, turning them into hollow) Portmen

They were people
No, here you are wrong, Gwyn was not a man, like those who found the souls of the masters in the flame, Gwynne is the nephew of the god Lloyd, so he was originally a god. In general, all significant figures from the time of the war with dragons, gods or half-gods. And in general, where did you get the idea that if a person is, then necessarily the darkness inside? I explained that the arrival of darkness foreshadows the era of people and this is only because there will be no overlords, but people will rule.
