I don't think she was mean, she offered her stuff or gave expensive items away to her classmates just because they asked. I think it's because of the relationship with her uncle and how he blames her for their death and that's why she moved out of house
My theory is, she was a rich mean girl when her parents were still alive, on the night her parents died they probably asked her to do/ go/ come somewhere/something but she refused and they does. So she blames herself and is now redeeming herself or punishing herself
