I deal with a lot of extremely abusive parents while mentoring refugee families. In the twisted thinking of the abusers, they always think they're doing the right thing. It often escalates from verbal and emotional abuse to physical, to death threats, and occasionally to homicide. We've had some notable cases around here. A habitually abusive dad beat his 9-year-old son with a baseball bat until he broke every bone in his body. In jail for murder, he's still claiming it was the kid's fault because he didn't do his homework (the kid's teacher says he was always on-point with his work). In another family-abuse homicide the dad is still saying that it was his wife's fault he killed her and cut her head off (she had asked for a divorce because of his abuse).
In the case you mentioned, the mom might have thought she was protecting her kids from the government. Abusers think they own their victims, and faced with forced separation they often think "If I can't have you, nobody will."
This book has a lot of case histories of family abuse homicides: "No Visible Bruises," by Rachel Louise Snyder. It happens every day.
I hope that’s not the case but it is a fear especially the way it acted last night definite a possibility that is the problem.. I have not looked into finding one yet this is a whirlpool duet about 5 yrs old at most I’d hate to have to scrap it
