Sure, the problem is there is level of flaw to character like recklessness, certain disregard for rules, short-temperedness... Etc that's associated. There is also the inherent solitude . If you round him up, have him think he knows better and should be preaching you naturally have a superdad. That's the general tendency with the character. Fans eagerly want the character to tame itself and remove the dangerous aspect far too quickly. They wrinkle their nose when superman is reckless. For example, seeing this as out of character.
They do it as well. Superman becomes this flying paragon of virtues and is seen in that context only. And then what? We hit dead end?Moreover, it takes hell of a time for a person to develop and somepeople don't change or shoulders change . Superman should have that dangerous aspect to the character,not just the kind-caring aspect. If you don't you are left with a bland character. Finally,virtues and vices are interchangeable to begin with depending on the context. Virtues can become vices and vice-versa. Superman's recklessness makes him act. It can solve problems and get him into problems. If you remove that, he doesn't act and is entirely complacent. He will be well rounded. But, would lose that sharpness as character.So, sometimes that kind of negotiations shouldn't happen at all. But, that's what happens. Fans make a fuss about superman being "dick" . But, Can you imagine a superman who doesn't break chains or a luffy that doesn't punch a strong wall?
I guess, what i am saying is. Superman is a wild white wolf. He shouldn't get too tame.
