Yeesh. Dude. You can't just editorialize the evidence when people are being persuaded by things that aren't in any of these videos.
Video 1: A lot of the time the gods are metaphors, and stories about the corruption of power. When you have that much power, that much absolute control, it's very easy to start sliding and Kratos was the example of "how much can he fall when he's given that much power" and he ended up becoming worse than Ares. She [Athena] was selfless, she died protecting Zeus, but in that selfless act she was the first god to be selfless, and that allowed her to ascend to a higher plane. She ended up going to a place that was higher than everybody else, and it totally messes with her head. She becomes just as bad as everybody else because she experiences a power greater than everybody, so it is always that kind of message."
Video 2: The arc of Athena was the most important arc of the entire series -- to show that she was the one greek god that did something selfless: she sacrificed herself to protect Zeus, and that actually allowed her to ascend to a higher realm, and she ended up realizing "oh look, there's more power up here" so it sort of corrupts her a little bit and she's sort of orchestrating the demise of the other gods.
Where does "unreachability" and "completely transcends" come from
@Georredannea15?
I mean, if that is an explanation that doesn't require QS, then we absolutely shouldn't assume QS. I don't see how "an infinite jump in power" is preferable to a different explanation like "this realm has some property that only allows specific people to enter." In Athena's case, she got there by committing a selfless act.
