This is placing a much higher standard on robots than humans are held to: to demonstrate that robots have to make hard decisions you presented a scenario where a human making either decision would have socially acceptable justifications available. But that just may be the key: maybe robots don't have to have superhuman decision making as long as they can produce humanly acceptable justifications for their decisions. That might still be hard, but at least you don't have to do that in a split second.
