You got it all wrong!!!
He wont kill you...he'll just drive insane forever and condem you to a mental asylum

That is not what I ment....I wrote clearly (just using an anology) that we in the eyes of the Outer gods are less than nothing. And their presence is enough to kill us or drive us insane. Willet kills Curwen just by reversing his spell. Curwen used the "head of the dragon" and Willtet used the "tail of the dragon", both symbols of Yog-Sothoth. His personal alpha and omega as you could say (I even think that this was Lovecraft cleverly mocking the bible) . Read your Lovecraft better. Also:
"It was an All-in-One and One-in-All of limitless being and self — not merely a thing of one Space-Time continuum, but allied to the ultimate animating essence of existence's whole unbounded sweep — the last, utter sweep which has no confines and which outreaches fancy and mathematics alike. It was perhaps that which certain secret cults of earth have whispered of as YOG-SOTHOTH, and which has been a deity under other names; that which the crustaceans of Yuggoth worship as the Beyond-One, and which the vaporous brains of the spiral nebulae know by an untranslatable Sign. "
So HM can try but In Lovecraftian universe he could be compared to Cthulhu at best.
And Lovecraft himself repeatedly said that the Old Gods are not evil. They are chaotic,entropy incarnate, not carring and endless like the Universe itself. He was a pesimist and an atheist. He mocked the ideal of moralitty and good vs evil struggle that we have invented.
On a side note. What I saw on various videos on YT with Lovecraftian vibe is:
Lurkers are clearly deep ones.
Seekers can be a cross reference between Cthulhu and The Elder things.
