But there's only one god running around doing things, and his followers are adamant that they are fighting for good. It's part of the sales pitch. But what he demands of them is mostly evil things. I don't think it is a coincidence that what Ser Davos said about the Lol is actually the first time I've ever heard anyone making that same connection. Why did this evil bastard bring Jon back? He's like the Little Finger of gods.
LoL is the new monotheistic god, right? maybe he's still on his Old Testament era here, having closer involvements in the going ons of things
The Seven (and by their extension, the Sparrows and the Septs) are the old polytheistic religion, they are farther by feelings but their followers and priests are still doing a lot of damage in the world
then there was the Old Religion of the Children, which basically has passed into folklore and old wives tales and stuff, like the mysticism of old that predated even the polytheistic system
anyway, i think LoL is mostly doing a lot of self-promotion and i never see him as a force of good. he is an ambitious power and he seeks to 'win' out in the religion war of the people of westeros. bringing jon back may further his cause, is all.
