Underlining the Monsters

One of the issues I've come across Lovecraft's pantheon is the similarities in the gods. Take the Greek gods for example, Zeus is often portrayed with a large white beard and is associated with lightning. Poiseidon is usually pictured with a trident and so on and do forth. Despite similarities in powers and  appearance, they share distinct characteristics that seperate them. That's not always the case with Eldritch gods. Which one causes you to go insane? Well, they all do that. Which god can't you to look at? Again, all of them. All these gods xause madness, bring ruin, and are beyond comprehension. There are gods that have assigned roles like Cthulhu being trapped under water, but that domain is shared with Dagon. It might make more sense if one was freshwater or saltwater based. Other gods like Shub-Niggurath usually hold the role of fertility goddess, but none of her stories paint her in that role. In fact, "The Dunwich Horror" is about spawn of Yog-Sothoth, the god of knowledge (if you can call him that.) Many gods in the Greek pantheon share similar story attributes like most heroes being descended from gods but most of Lovecraft stories show humans as victims of the gods, similar to the Greek gods constant interference with mortals. It's hard to put gods in a place of understanding when each god causes the same thing: madness. Maybe that's the point. These aren't benevolent creatures but beings that exist beyond our reasoning. You can't add human characteristics to them which makes the impossible to be relatable. Categorizing them would be an error and disservice.
