The word “hubris” in regards to Kemeticism isn’t even appropriate, like, ever.
In The Pyramid Texts and likewise texts, the dead person literally fucking claims to BE certain gods (“I am Atum! I am Shu!”), be a unique god themselves, and exceed (some of) the gods in power. There’s also the thing where it says “O goddess Nut, we all know that you love (dead person) more than you love your Mother Tefnut.”
The ancient Egyptians were practically the DEFINITION of hubris. Modern Kemetics actually don’t really even measure up to the levels of “hubris” that the ancient Egyptians portrayed (which wouldn’t even be a bad thing since it’d just be being historically accurate). So applying the same standards to modern Kemetics and modern Hellenics is absurd if you want to be historically accurate. The Kemetics and Hellenics were VERY different.
