Coriolanus learns that he cannot trust anyone, because it can be a weakness. However, this is a flawed conception because, throughout the book, he constantly needs help from others. The moral is most likely that it is important to trust others, even though the main character is against it. We can tell that the moral is different from what the main character learns because the main character is seen to be a morally unstable and corrupt individual, which becomes more and more prevalent as the book progresses.
