Boo hoo. They are not the good guys. If there's one thing you should have taken away from New Vegas, it is this: "No matter what it looks like, it's all government and none of it works." Sure, the Capital Wasteland chapter was really altruistic and that's mostly due to the fact that Bethesda could not write well if their lives depended on it. But, the Mojave chapter, after years upon years of being beaten down by the NCR and other encroaching factions, has grown to be nothing more than a bunch of greedy, incestuous, xenophobic technocrats. Also, in Fallout 1 and 2, the BoS were far from the good guys.
