Maybe that was the point. The tunnelers represented a nihilistic worldview, one in which every action you take ultimately doesn't matter as, eventually, all will die, and all change wrought will be forgotten. Maybe the game challenges your ideology, asking if in the face of insurmountable odds, you would still attempt to affect change on your surroundings, or if you'd just give up.

I think the Fallout games excel at morally gray choices. That's part of their charm.

Then again, some of their morality system doesn't work right, like in FO3 where I became super evil form killing everyone in Megaton and taking their stuff before blowing them up instead of just blowing them up.
