Bill and Semph are acting out of the same rough motivations. “I love everyone in the world. I do. So help me God, I love you, all of you!” = “Then you’ll forgive me, Linah, because I love my fellow man, too. Whenever he was, wherever he is; I have to, I work in an inhuman field, and I have to cling to that. So… you’ll forgive me…” Both are unleashing evil on others because of a sense of love for others (hence Bill's face and Semph's statue having the same expression). In Semph's case there seems to be a sane moral dilemma to be had from all this, but is there really? His work causes much more damage than Bill's actions. From a utilitarian perspective Semph is much worse than Bill, as is Linah. We automatically see them as the "sane" ones in this composition, but are they really? Please forgive my rough analysis, I'm recovering from a bad case of food poisoning and am very much out of it.
