Also, what's with the hate on the East Coast Enclave? They're WAY more "shades of gray" than the West Coast Enclave. I always see people claim that the East Coast Enclave is like "saturday morning cartoon villain" evil, but the Western Enclave were the ones who wanted to disseminate FEV throughout the entire globe...the Eastern Enclave were just trying to seize a purifier so they could restore order in DC. Their methods were quite brutal, no arguing that, but they weren't trying to wipe out the population; Eden was.
I think it's because we got a glimpse at the human side of the west coast Enclave a few times in Fallout 2 (and definitely in New Vegas), while in Fallout 3 all of them are either trying to kill you, throwing tantrums and shooting people, or are cold, calculating computers. In Fallout 2 you had a male Enclave scientist who had a crush on a female soldier and referred to her as some pet name (forgot what it was), a couple mechanics feuding, a deserter giving his honest opinion of the organization, a brownie nosing sergeant, a gossiping cook, etc. They felt like people. The former Enclave members you encounter in Fallout: New Vegas are the same way.
In Fallout 3 you never really get to see the human side of the Enclave. Autumn is the closest thing to a human side we see, and even he just throws tantrums and shoots people most of the time. Now their portrayal in Fallout 2 wasn't perfect, Frank Horrigan was a pretty straight forward psychopath, but they still seemed more human; even the President regretted what he felt he had to do. In Fallout 3 the Enclave members might as well have all been machines, and it's difficult to see a machine as morally gray since machines don't really have a conscience.
Overall I don't really consider either portrayal particularly "gray", but the west coast Enclave certainly seems more human than the east coast Enclave, so if I
had to pick one I'd go with the former. That's my opinion on the matter, anyway.
