Rogers is a man out of time who never felt at home anywhere even back in his own time, and who has become addicted to war because it is the only place he ever had purpose and belonging. Thor is really the only guy who seems content with his lot, and basically just wants to preserve what he has, and is mostly fighting to keep what he has from slipping through his fingers. He has the least amount of angst, which is probably why he needs Loki to work as a character.
Angst is a Marvel staple. Netflix characters might have it slightly worse, because they are mostly poor people, and because the very serial nature of their stories leads to the angst being lingered on. In a movie, the angst is only going to be showed long enough to establish it as one plot-point in a chain of plot-points. In a series, entire episodes are likely to explore that angst.
