No doubt, but it also said aloud what no one would dare say when it was happening. Oppy became a sacrificial lamb to salve our collective conscience for what we did to Japan. To make that point with maximum impact, the storyteller needed to lay the extensive and complicated groundwork required for their audience to appreciate mankind's tendency to crucify our saviors.
It's not unlike handing down the death penalty, and then spending decades revisiting that decision. we want the visceral rush of revenge, but we also want to sleep at night. Strictly a personal opinion, but life without parole is a much harsher penalty than being put to death. I understand there are innocents on death row, but it is the system we labor under so we must be pragmatic enough to accept the imperfect judgment of imperfect human beings, or we need to be courageous enough to admit revenge may feel good (at least for a minute), but it never really solves anything so maybe we should admit that fact and move beyond the desire to seek it.
