Perfect place for it. Makes those movies super-creepy.
Especially considering the fact it's "real" – in the sense that people believe it in the real world, and think it's good, while nobody thinks Michael Myers actually exists.
It's a horror story we're surrounded by, not just something the writers came up with for the film. With menacing symbols, demented rituals, blood-thirsty villains masquerading as benevolent, and a pervasive sense of fear that permeates the world of the faithful.
Not to mention centuries of horrific death, torture and destruction it has already wrought that forms a long, sordid tradition of bloody prequels.
The Dark Lord Yahweh is perhaps the most popular horror story villain of all time. Not very well written, but astonishingly successful nonetheless.
