I don't understand your analogy to Oppenheimer and Truman. My prosecutor's argument is that the monster, as a creation of a person, is a machine and therefore has no conscious, and therefore can't be guilty, so the guilt has to lie with Dr. Frankenstein. (I don't subscribe to this theory, by the way, it's just how I imagine myself as a prosecutor arguing it.) Who is Oppenheimer in your analogy and who is Truman?
