Also, saying that there's no altruism? The second she learns the Kree are the bad guys, she abandons them, the only people she had ever known, in order to do the right thing. How is that not altruistic? She blasts Yon-Rogg to hell, even though she kind-of-sort-of had a thing with him, because he wanted to enslave the Skrulls. She does this without second thought. When she thinks the Skrulls are the bad guys, she chases them down on Earth, trying not only to stop them, but to protect humans as well (think about the chase scene between her, the Skrulls, and SHIELD).
"I have nothing to prove to you" is definitely very inspiring as well.
What exactly does Carol do that's selfish? She destroys a jukebox and steals a motorcycle, and those are like the only two slightly not-good things she does. And as I explained, she's not one-dimensional. She was just trained not to show her emotions, and that's the whole point of her character arc in the movie. We see in Endgame she's a lot better with her emotions, able to channel her anger in the fight against Thanos (which we now know was very personal).
