To me, one of the biggest themes of the story is morality. The people being experimented on are criminals, but they are still being tortured, emotionally and physically. At the end, Jeff is asked to give the scientists permission to put someone through extreme pain. He is hesitant to do it, but he finally gives in. When it kills her and he asked to do it again to someone else, he refuses, ending his own life instead. It’s a very dark story line, but a very important one because Jeff finds a way to escape from the darkness of the power binary he is in. The story ends with Jeff’s final thoughts; “I was happy, so happy, because for the first time in years, and forevermore, I had not killed, and never would.” He finds joy in his own death because by finding his humanity, he is able to escape.
