Who's the most heroic MCU hero?

This is why MCU is so lame. Their most "heroic" hero is a guy who:

1. Couldn't pass the physical to get into the Army because he was too lazy to exercise and train like the other soldiers did.
2. Stole the rank of Captain from other more experienced and more qualified officers who had worked their butts off for many years to put themselves in line for a promotion.
3. Obstructed justice and became an accessory to murder by aiding and abetting a double-murderer to escape from the authorities.
4. Acts like a tyrant who believes that he shouldn't have to answer to the people and that he alone should decide what's best for the people.
