That's a great thought, narya.
Even I, who tend to the center of most RL social situations, tend to see pretty black and white in Tolkien's World. It's such a relief, really! I often, in RL, look with doe eyes at the people who are
so sure that they are right, in real life situations. They are
so sure that the other side is so clearly wrong (on all points, btw). I feel that that sort of social clarity would truly be an emotional blessing. I'm not sure it's fair or realistic, but it would be easier.
In Tolkien's created world, I have the luxury of black and white. And I indulge myself with it! It is difficult for even me to see the point of view, and sympathize with, for example, the orcs. Tolkien tried to create them as purely evil creatures, I think.
Thoughtlessly evil, which is particularly chilling. If you create a beast, you can make it one-note. People are not one-note. People are harder to compartmentalize than orcs. Darn them.
Thank goodness for orcs, really. They are a relief, a break from the real life task of realizing that different points of view do not necessarily fall along the clear fault lines of Right and Wrong. All those cowboy and Indian movies I saw when I was a kid, when the cowboys were valiant and the Indians were mindless savages? That whole picture looks a little different to me now.
It was fun, then, easy, to know who the heroes were. Real life sometimes doesn't afford you that luxury.
