The essay appears at the "Tom Dispatch" website. It is introduced by Tom Englehardt and written by Ariel Dorfman, an aging playwright and scholar from Duke University whose native country is Chile. Title? "A Tale Of Torture And Forgiveness."
I urge you to read this essay, but I feel that I must hasten to offer a re-assurance: it is "safe" to read: No "Bible-believing Christians" were harmed in the making of this essay. This is about torture practiced by "the bad guys" -- or alternatively, one particular bad guy -- in a forgotten world far, far away from our own: the context is southeast Asia during World War II and the local conditions are things like the Bridge on the River Kwai. (You may remember the movie.)
It is also about forgiveness as practiced by a "good guy," Eric Lomax, who was an officer in the British army, and what it cost him. Please read it -- but notice that I did not say, "Enjoy." Or, "Blessings."
