Ancient Cthulhu, Lovecraft’s demon/god/alien, represents a universe profoundly indifferent to human life. Cthulhu’s evil is not the Christian evil that specifically targets the human — like the devil, who spends his time prospecting for souls — but a more unsettling impersonal malevolence that simply fails to register anything of value or interest in our species. This is the impersonal malevolence of billions of icy planets, of trillions of miles of space, of primordial rock formations under the sea. They don’t care about us.
