The joy of the comic is that we all get to be with Superman at that moment. Learn the lessons and you really will be a better person for being in his presence.
Fiction is of course fake, but it can be a guide to what to do and what not to do in our own world so that we can make it a better place.
If you want to make good real then commit yourself to being good to the people you meet. Remember, Superman might not be real, but Mr Rogers was and he was more moral than Superman.
Live the life you want to respect.
