oh, i think i didn't make myself clear enough. i didn't say that superman should be perfect. he isn't perfect as a matter of fact. he has faults.
i just said that he isn't one of us. he isn't a layman like us who concern about the daily issues and meeting ends.
he feels pain. but not the way of pain we feel.
i said he has a 'higher' understanding of life. he is 'sorta' like a freak or a genius, whose thinking is kinda 'unique' to us. we would go "what the heck!!!???" to some of his response to certain issues, but there is a deeper meaning in his response.
besides, the character development on the main character like u said on spidey and luke; i would like to see the character grown on the people around superman/clark kent, that they have been inspired by his 'thinking'.
If we go by those standards for Superman, then we have exactly what Jor-el wanted for Superman in the Donner Era, which in my honest opinion, is too much to ask for considering how the character has changed in the comics since then.
If my memory serves me correct, given how Superman has been written within the last 2-3 decades (where Clark is the predominant Persona), although Superman may appear god like, he was still raised with the mindset of a human being.
One of his most notable issues that hes struggled with in life has always been his feeling of loneliness, of being the last of his kind and not really having someone to talk to when he was growing up who he could truly relate with. Then theres the fear that Im sure a lot of us have felt that Superman has been known to have, and that is the fear of ending up alone in life.
Sure, he doesnt worry about things like meeting his bills and rent on time like a lot of us do, but he can get frustrated over the some of same things that we do as well; heck, as much as Clark loves Lois or respects Batman/WW, they all end up frustrating him at times with their antics.
I also remember reading a issue where Clark was stressed about meeting a deadline for a article due to having to work and balance it out with his heroic duties as well.
And Im sure that prior towards becoming Superman, that like all of us have asked ourselves, he had wondered on what or who he would end up becoming in life when he was growing up, especially with powers like his and how hed fit in society.
