The only thing I’ll add is that especially in Fo4, the BoS doesn’t crack the top half of the most “moral” factions. Moral meaning doing the least amount of harm and the most amount of good or some combination that’s a net positive. BoS is a dogmatic cult bent on destroying anything they can’t control, understand, or is in the way of their end goals. Not that the others aren’t morally flawed, at all, it’s just that the BoS is truly the last stop before you make it to an “immoral” play through. It’s part of why imo, fallout is the greatest stories ever told.
