In fiction, the mad scientist tends to put himself in the role of God which can be an extension of the differences between religion and science, as exemplified in the discussions of evolution - which is a theme used by mad scientists who create beasts and fantastic monsters. When his monster was born, Victor Frankenstein shouted, "Now I know how God feels!" This makes it fit perfectly in option D of the question.
