Behind the jokes and badassness, Captain Marvel is a fascinating character to me, because of how death follows her.
She causes an explosion. That explosion, which gives her powers and her immortality, canonically kills her. The Kree Empire resurrects her and makes her as Kree as they can. She shares Yon-Rogg's blood and his life, she's his creation, she's his victim, she's the one who causes his downfall, she's the one that destroys the system, the society, the planet that allowed her to be abused.
It's the Kree that see her as a killer and Annihilator. She's a monster of their own making, but it influences every species and planet she touches. Her victories cause death and her mistakes cause more death. Carol's triumph, the death of the Supreme Intelligence, results in the death of probably millions of Kree, and by consequence, almost causes the death of Hala's star.
"I'm only human" Carol says, before killing the Empire that is the reason that she can't ever be human again.
"We'll be back for the weapon," Ronan says, but that weapon will kill everything he stands for.
"Your life began the day it nearly ended," The Supreme Intelligence says, coldly, calculatingly. It's an AI. It doesn't have a good concept of death. It doesn't fully grasp that Carol had genuinely been killed that day, because she's still in front of it. Carol kills it.
"Death seems to follow you," Dar-Benn says, before she causes an explosion with the bangles, trying to defeat Carol. The explosion kills Dar-Benn.
Death follows Carol. Death follows Carol! Mar-Vell is dead. Maria is dead. Talos is dead. Soren is dead. Ronan is dead. Minn-Erva is dead. Korath is dead. Dar-Benn is dead. Yon-Rogg is, probably, dead. The Supreme Intelligence is dead. Natasha is dead. Tony is dead.
The only people in Carol's life who aren't dead are Kamala, Monica, Yan, Valkyrie, and Fury.
She watches helplessly as Dar-Benn almost murders Kamala after Kamala tries to save Dar-Benn's life, tries to find a way to solve the violence without death.
She watches helplessly as Monica gets torn into another reality, which for all she knows, she could die in. The tear in reality that was caused by Dar-Benn's death.
She tries to hide Yan's existence from her friends and tries to warn him and his people. The Kree soldiers aren't fighting to maim, they're fighting to kill. He escapes death by his own fighting skills and the fact that the Kree would rather focus on killing Carol than him.
Valkyrie and Carol interact once, and she only calls when she needs help after a fight, not during. Think about it. Valkyrie and the Bifrost could have helped the trio enormously. But Carol doesn't call until the fights are over. It would be very easy for a regular Asgardian warrior to die compared to superhumans.
And Fury... have you seen how often Fury comes close to dying? He's alive from skill and luck. He is lucky that he isn't dead.
Captain Marvel is so, so fascinating. Her story begins with her own death, and the more it goes on, the more death happens around her. Nobody is safe. She causes almost all of them, even the ones of her friends - not directly, but through the consequences of her actions. The consequences of her victories and mistakes. The consequences of her anger and revenge, her power and powerlessness. It is caused by both the Human and Kree sides of her, by both Carol and Vers, Captain Marvel and the Annihilator.
Carol is immortal. She can't die. And death follows her anyway.
