I just want to ask something...

Recently, My Aunt told me about her child being rebellious.

1. Her 2nd Child cursed her because her 2nd child and eldest child have fought because of their love lives and house chores.

2. Then her youngest child told their family that he will kill them during their bedtime.

This really freaks me out and her children are one of our best cousins, I have (especially the youngest child)

Are they suffering in mental health??
