Has there ever ever been a more selfish character than Ellie?

Nothing against Bella Ramsey, I'm talking about Ellie the character. Like, this girl has the immunity in her blood that could save THE ENTIRE HUMAN SPECIES, but instead of finding a lab and trying to save mankind, she covers the bites and goes off on vengeance missions that will surely eventually kill her, and all of human hope. Shocking. I actually want her to get eaten 🤣🤣
