I prefer the William Shatner version of "Common People". No, I'm not kidding.
Captain America from the Marvel movies. First, he gives Tony a self-righteous speech about how Tony "Isn't the guy to sacrifice himself", which Tony proves wrong in the same movie by flying a nuclear bomb into a wormhole, not expecting to return. Then, in Civil War, he drags Scot, Wanda, Sam and Clint into to his 'let's demolish an airport while shielding Bucky' crusade, then leaves them to get arrested while he and Bucky escape. Then in Endgame, Tony sacrifices himself to save the entire universe, while Steve abandons his friends and duties to live in the past with Peggy. Don't get me started on Cap living the apple pie life while Bucky was being tortured.
