R. Daneel and character development

R. Daneel's monologue at the very end is a great example of the kind of lessons that can only learned through experience. R. Daneel learns that "the destruction of what should not be, that is, the destruction of what you people call evil, is less just and desirable than the conversion of this evil into what you call good" which is a lesson that is impossible to be taught through words alone (270). Also, R. Daneel basically learned how to manipulate human beings in the name of justice. Daneel also seems to learn the concept of spiritual evil because he uses the word "sin" which is an impossible concept for him to understand because it means that R. Daneel was able to understand that evil is more than just a bad or harmful action (270). All in all, the robot finally started some character development though it happened at the end of the [first] book.
