Most surely he used pity to convey what its meaning held to the story. I do not know when Aragorn could show pity to an Orc or to the Nazgul, for they were bent on destruction. A gollum character is far more close to what we see in everyday life. A twisted soul who is radicaly evil, who has murdered, and does deserve death. I know we are not to being politics into this forum, but the Professor does make us ponder the question of captial punishment. Some deserve life who are dead and some who are alive deserve to die, can you give it to them? Do not be so quick to hand out death and judgement, for not even the truly wise can see all ends.
In our time this is the question from New York City to Madrid to London, and to the streets of Jerusalem.
Bruce, we're not opposed to a respectful discussion of political issues here, so let's have at it! I agree that Tolkien's quote here has direct implications for capital punishment. I wonder if there was any opposition to the death penalty in England at the time? I don't think he writes about this in the letters. But he DOES write about the anti-German sentiment in England, I think after WWII. (Again, I apologize: I have loaned my copy of the Letters out, and it does not look like it will ever be returned!) Some in England thought that Germany should be wiped off the face of the earth in retribution. Tolkien recognized this for what it was, and his position was probably not very popular.
Your last point is well taken: wouldn't the world be much closer to Peace on Earth in this season if vengeance for past harm were replaced with Pity? Having been through two World Wars, I don't think we can call Tolkien a bleeding heart pacificist. But I think his views are reasonable and principled.
