Which other characters develop the theme? Johannes: Because David grows up without his parents, Johannes is the one who teaches David this principle of treating others as you would want to be treated. Another example of how Johannes teaches David about respecting others is when David reflects on his lack of forgiveness towards Carlo. David remembers Johannes teaching him that, "There's always some way in which you're at fault, too, and you must discover that fault and learn to recognize it and take the consequences... not only because it's the only honourable thing to do, but it's the easier way. You can't change others, but you can do something about a fault in yourself." (pg 168)
