In Lovecraft's world Cosmic horrors are not beyond human comprehension. It's just seeing them is so awful and paradigm-changing that going insane or killing oneself is the better choice when confronted with those truths. I conclude it based on the few paragraphs of Call of Cthulhu where narrator says that when humanity pieces together the disjointed pieces of knowledge they have obtained it will destroy them.
Anyway, I think it's ridiculous how much js sites have nowadays (probably due to it loading them on e-book eats battery so much)
They literally exist to just draw buttons and stuff!
