This? This is why I have a headcanon in MCU that Clint is just as big a Cap fan as Phil (he’s just quieter about it), because that is one role model he can look up to when his entire life went to hell in a hand basket. When Nick recruited him, he thought it was just another job to avoid jail time that pays much better. It wasn’t until he met Phil, who lived by a code inspired by Cap that he decided to stay.
I completely agree.
Cap is a decent, upright man of morals, someone for a young boy missing that sort of figure in his life to look up to. And I imagine a boy from an abusive background would idolize a man who doesn’t like bullies but puts then in their place without becoming just like them.
