She didn't bully Anne into stealing the box, if she bullied her into doing it Anne would've probably rejected her idea. It's not just that though, the worst part about Sasha's influence is that she's a rule breaker. She spray paints graffiti without permission, she skips school over false claims, she steals money, she puts people in harms way whenever she does a dangerous activity, and she pressures other people into getting what she wants. I understand people think Sasha has a chance to change her ways, but things rarely ever happen in the snap of a finger.
