Yes this is true, she’s not for attacking but she will defend and if that means causing harm to keep someone innocent safe- harm to the bully’s could come as a happenstance or by product of her defense.
I wouldn’t expect it, but when in drastic situations like this it could happen as a necessary element of keeping someone safe.
Regardless of whether or not you attack for revenge, this servitor would useful for helping your nephew in the meantime. @YHWH
Get the book Angels of Wrath. Do the Destroy Defenses, and Binding rituals to start. Then the rest as applies to you. This book has never failed me yet in dealing with bullies - I’ve had to deal with several in work situations.
Also, get Lucifer and the Hidden Demons. Many rituals in there that can help. I often combine rituals from these 2 books on a target and works very well.
