Steve Rogers said he was “just a kid from Brooklyn”, and that is simply the best way to describe him. For all that he becomes, he still is, essentially, just a kid. He has high ideals, that might seem outdated and ridiculous, but he is a man of morals and he won’t do anything to compromise them. He believes in sacrifice and doing things for the greater good that he can be easily angered when he believes someone is being self-centered and would never do something if it meant they could potentially get hurt. If he doesn’t die and instead gets frozen in a block of ice that would be okay too.
