[Evisse the Blue]

If I may take a slightly different viewpoint here:

This experiment was less about seeing how far people would generally go, and more about how far would people go under what circumstances. For instance, a variable that was manipulated during the experiment you mentioned was the look of the building in which it took place. If it looked very professional, the subjects were much more likely to obey; as oposed to it looking like an old decrepit building... (Another variable which was manipulated was the number of people in the room with the subject, besides the 'victim' and the experimenter.)The point being, people are more likely to act in a certain way in a certain context, because it helps them 'play the part' that was assigned to them more easily. In other words, these same people who pushed the limits of cruelty to shocking levels were good citizens, good neighbours and good spouses in other contexts.

Now, this is not consistent at all with Tolkien's viewpoint: according to him, someone was good, regardless of the situation into which he found himself at one point. Nor is anything in his work ever to be blamed on minor details, such as the number of people backing Aragorn up when he went through the Paths of the Dead. He shows the same strength of character and other qualities that he has, scorned by Barliman, distrusted by Sam, praised by the people of Minas Tirith. He and the rest of the good characters in Tolkien's world have no doubt about the right path, and they walk it no matter what. The bad characters as well, choose to walk the wrong path, without ever straying. So there is hardly ever any 'grey'.

While even the best of us in the world we live in nowadays are straying, distracted by minor details, living in a twilight of doubt as to which side we are actually on.
