I say Eden was the one derranged. Talking of rebuilding America as it was, trying to get the wastelanders on his side, only to try and kill them all. I never got the impression in Fallout 2 that the Enclave's goals were to rebuild America as it was.
Eden's equally a loser, he allowed the Lone Wanderer to go to town on his own people when he had the power to stop it all. I don't even understand the concept of Enclave radio, considering that Eden himself had absolutely zero intention of co-operation with the wastelanders; the show had been going on for years right and Autumn only convinced Eden to "abandon" the FEV plot "months ago". As far as I am concerned it was Eden putting his equally derranged ego above national security.
I got the impression that Augustus wanted to work with the people of the wasteland in order to rebuild but Eden was the one that lied to and betrayed, not Augustus. It gets confusing later because Bethesda's very bad writing. Augustus rebels but then talks of being loyal and what not to Eden.
I got the impression that there's obvious more to the dynamics between Eden and Autumn and their relationship than we know. I believe that Autumn's pledges of loyalty and incredulity at Eden's deception only tie into his madness; I think that he had a plan for the Enclave but, for what-ever reason, wanted Eden to be a part of it - almost like, given time, Eden would "come around to his way" or something. Frankly it's also why I believe that, even in success, Autumn's goals would fail... some small comfort given I don't like Eden either.
And on the talk of betrayal, Autumn's only true obligation was too his fellows whom he [censored] up entirely.
I also don't see how working with wastelanders is a bad thing. The Enclave worked with a mob family in Reno supplying them with chemicals and energy weapons. Then there is that encounter of Frank and two Enclave guards trying to convince that farmer to come and work with the Enclave. The guy says he rather die then work with the Enclave. So he is killed for it. There are some people in Fallout 3 broken steal that seem like wastelanders to me working for the Enclave.
Yeah but the Salvatore's were disposible assets and were being very muched ripped off; they were trading chemicals for a weapon that would kill them too, Richardson himself says "So what if the mutant mobsters kill each-other, saves us from doing it." (maybe minor variation).
Objectively, working with the mainlanders isn't a bad thing but it's not likely too happen; I can't imagine that anyone still in the Enclave now being anything other than embittered and deeply resentful - anyone feeling the same towards the Enclave itself will have likely just deserted. Don't forget that the Enclave are neither normal or particularly rational people, they've all been essentially indoctrinated into the Cult of Eden; hell Moreno is still loyal to the Enclave 30 years after the fact and old man Kreger is quickly persued by the notion of "payback" against the NCR.
Anyways I hope Augustus is alive and out there somewhere. Maybe back in Chicago working with Barnaky's Midwestern Brotherhood of Steel
The Enclave can do what they like, I hope that Autumn is lynched personally; though, based on my interpretation of the Enclave, he likely won't be.
