Well the rest of the cult (are they the rest of the cult we're never really told that, we can only guess) seems to have died (probably-sam tuttle, the ledouxs, Sheriff ted childress, rev eddie tuttle and or moved on like the senator (and are they really the rest of it? ) so I dont think its still active and all that's left is a retarded big fat hillbilly who likes killing.
BUT I would have been okay with that had there been just a little something, almost anything, explaining that that is what happened or at least reminding us that it is the case. Maybe a photograph of these people after a deer hunt or something like that with cohle and hart figuring out who they were. Something, anything, not a just dead air and a "you figure it out"
the two victims were displayed for the world to see Because Erroll is crazy. He ‘broke bad’ from the cult by killing and displaying Dora Lange’s body, which launched the initial investigation. The Tuttle’s tried their best to put the toothpaste back in the tube, but it was too late. Billy Lee, I’m guessing, kept Erroll on a short leash after that point. Once Billy Lee died, Erroll was left to his own devices again and that’s what lead to the latest killing being out in the open again.
I like that explanation a lot and its very similar to what I theorized as to what might have happened. But again. Could they have just put something in at the end, again, anything, to confirm and remind us, even hint at that? It would have made it so much more satisfying IMO.
For what it’s worth.
I think I nailed the final episode:

From my perspective, the series is ALL ABOUT COHLE and more importantly, what Cohle believes. The murders/abuse/drugs/violence/degradation/conspiracy etc, are all contributing factors that have formed his belief system. A system of belief that has it’s roots in the death of his child. I’m not suggesting that Cohle will be going on the road with the Preacher, but if he is forced to accept “Satan” as a real force, then he must also accept God.
IMHO, this is what the final episode will be about.
