She'll feel bad about it on her own once she's not angry anymore. Especially when she learns it didn't even further her goals. The second worst thing you can do is to also get angry or punish her, which will only make her feel justified and not question herself. The worst would be giving her what she wanted. That's not the lesson you want to teach at all. So basically follow this father's lead and do nothing. Maybe talk about how it makes you feel once things calmed down.
