The Enclaves are the grasping remnants of the old pre-war American government. Given that they're 50% responsible for the Great War, they're not really standing well in anyone's eyes. I'm sure any wise wastelander would hold serious contempt for the Enclave, for what they've done to the world, more particularly North America. If the Enclave had tried to atone for the sins of the past, maybe they'd be redeemable. But they're repeating their same exact mistakes, and expecting a different result. No, they're not redeemable. I fuck with the Enclave, though. Their armor is badass.
