They're a dark nation that the wasteland needs to bring peace to the world and for society to rebuild under one rule.
I broke your argument.

the means can not justify the end and his means are evil or dark or evil
so he's evil.. screw what the legion will achieve (maybe) 50 years henceedit: I am not an NCR fan myself because they repeat mistakes from before the war but I am impressed by the way they have managed to become so big that it'll take something very significant to bring them down. Personally I thought Mr House's vision for the future (for the ends he has in mind) was cool because obviously the guy is a long term planner and what mankind needs is a few more visionaries like him


what if I put it like this: their actions cant be called anything but evil would you agree with that? they take slaves, kill merchants and civilians in NCR, kill their own people who have failed in battle etc etc (you know it's a long list)
