Captain America is more than just a superhero. He's Marvel's living embodiment of truth and justice, sworn to fight against evil wherever it may raise its ugly head. Unlike many other superheroes, however, Captain America doesn’t just fight against garden variety evil scientists and masked thugs. Captain America began as a superhero fighting against the forces of Adolf Hitler in World War II, which set the precedent for his entire career. Captain America's battles are against hatred, bigotry, and fascism, intangible concepts that can poison any country or people. It seems obvious for Captain America will always believe in freedom and compassion first but he hasn't always understood the nuances of hate and prejudice.
