But would she really have actively participated in Death Eater activities, and did she have the stomach (or the courage) to practice Dark Arts herself, and torture and kill people? I rather doubt that. I think she liked being a hanger-on, but she seems to be the sort who'd balk when it comes to getting her own hands dirty.
She's one of those characters with whom you could do almost anything. Her parents are never mentioned, and we never find out if she has siblings, so all we know about her is that she was a nasty "mean girl" as a teen. She might have been truly evil to the core, or she might just have been a spoiled brat. Maybe she continues being nasty and unpleasant as an adult, or maybe she grows up. Lots of people who were deeply unpleasant as teens become much more likeable adults.
