Also she actually had a scene earlier in the episode, so viewers could already assume what'd happen.
I know anons say it's because she's a female character, but while I think that's why they made her the most "good" one and had her explicitly say she's fine with dying, I don't think that has anything to do with the above. I mean, either way, she still fucking died.
