I absolutely think that they come into the GB as brainwashed as the rank and file, and as you said Lang, they are poorly educated and become drunk on power. I guess it takes a truly open-mined individual such as Franz to go, "wait a second, this doesn't add up and we could be hurting people here, maybe we should pause and regroup..."
But I still believe there's at least a couple who ARE evil and know what they're doing is wrong, I mean for Christ's sake, they knowingly joined the UN knowing how against principal that was. That to me spells intent. It's frustrating that these guys are so simple and yet they've caused so much damage. I just can't shake the feeling that there's something more at play.
