Y'all talk saying that IM always was willing to sacrifice his life, his drive though is ego, he wants to be remembered. He's not as noble as Cap, who in TFA, was willing to die to make sure no civilians suffered, despite his date too, he gave up a major part of his life. Then, in WS, after successfully saving the lives of many, including a Strange; from being killed by the helicarriers, he stopped even though the helicarrier he was on was being destroyed and falling apart, to save the life of Bucky by helping him when he was trapped so that he can be free without knowing if he'd be fine. Cap without a second thought, was willing to risk his life even though he knew that the helicarriers would target each other and destroy themselves. That is the true definition of a noble hero, who's behavior exemplifies justice and humanity. Not ego and greed, like piss poor IM.
