No not really. At least I think. The reason why is when you break it down the quest really had no alternative other than kill the ghouls, invade Tenpenny tower, or talk peacefully with Tenpenny and let them kill everyone in the tower. There was no option to ask Roy Phillips to relocate to Underworld in D.C since it's a ghoul community and he'd likely get along finely there. When you break it down it's still morally black and white that judges you for killing Roy or helping the ghouls who were eventually gonna kill everyone in the tower. A better to stay morally ambiguous is to offer no karma gain or loss regardless of decision and open the option to make Roy go to underworld. But he was a greedy sonofabitch. Compare to New Vegas, there's a hell of a lot of moral ambiguity in New Vegas that far overreaches Fallout 3.
