Much Motto.
"Not only is Captain America shocked by the world he's woken up in, he's ashamed that he wasn't there to fight for it. That's just amazing."
That's another important part of Steve/Cap. He humbles us. He humbles normal people, heroes and Gods. The fact that he's heroic, brave, smart and strong isn't even the main part that humbles people. It's the fact that he does it because he believes it's right. And he's not aware of those things, it comes naturally for him and most wish they were that kind of person.
There is this great moment in the "Maximum Carnage" storyline.(I wish I still had the GN) The masses of New York have had worst parts of themselves brought out by the psionic villainess Shriek. They are rioting throughout New York. The heroes are trying to put a stop to it. One man grabs a brick and screams about windows and mirrors always laughing at him and showing what a failure he is. As he's about to hurl the brick at a storefront, he sees Cap's reflection in the window. He turns around and then they lock eyes. He drops the brick and whispers, "I'm sorry" That is a prime example of the effect Cap has on people.
