When the emperor was divine ending

The ending of this book was pretty interesting. The beginning of the fathers confessions really capped off the ending of the book by giving the reader a sense of helplessness that was felt by most American-Japanese of the era. He was tired and hungry, so he used a false confession as a means to an end, by telling them exactly what they wanted to hear to determine his fate quicker, and get it over with either go home or accept punishment. There seems to be three parts to his confession. In the first part of the confession, the father starts to state just about everything that the American-Japenese (spies) were being accused of: "I poisoned your reserviors. I put insecticide in your food. I sent my peas and potatos to the market full of insecticide." ect. In the second part of the confession, he throws out as many roles of an everyday American he can possibly think of: "Who am I? You know who I am. Or you think you do. I'm your flourist. I'm your grocer. I'm your porter. I'm your waiter." etc.. Then in the final part of the confession, he starts to spit out all of the slang terms used to insult Asians: "I'm the one you call slits. I'm the one you call slopes. I'm the one you call yellowbelly. I'm The one you call a gook." and so on. At the very end  he said "And if they ask you someday what it was i most wanted to say, please tell them, if you would, it was this: I'm sorr. There. Thats it. I've said it. Now can I go? I found myself questioning alot about what was going on in this part (the ending) more so than any other part of the book, and still skeptical of what to make of it. In my opinion, he was simply laying all the cards out on the table for judgement. Again, he had seemingly given up hope and essentially just wanted fate to take its course.
