So Old I'm Losing Radiation Signs
It doesn't. Reminder that BoS fought the Super Mutants in Fallout 1 to protect themselves and possible technology, and not to protect the wasteland. Their reason to protect the wasteland in Fallout 3 makes no sense given that the East Coast BoS comes from the West Coast, the same BoS that fought only to protect themselves in basically the same situation.It's still transparent as to WHY Bethesda did this, but the point remains that it makes sense.
The only reason Bethesda made them want to protect the wasteland was to make them into paladins of good, completely contradicting their origins and their motives.
I could buy BoS going rogue wanting to protect the wasteland, but the reasoning here is thin and very weak.
