Totally disagree with your comment re good/bad parenting.
My mother treated both my sister and I the same .
I respect the law, never hit people (especially women) and try to be polite to everyone.
My sister is a criminal. Wanted by the police and when I caught her stealing cash from our mother and grandmother I kicked her out of the house. We never saw her again.
Some people just grow up bad. It is usually from the people that they mix with. Social media now is a BIG influence on kids.
People forget the innocent victims of crimes like this one. Parents, siblings, children etc.
I am not judging this kid's parents, but they will be hurting as well. Not the same as the family of the poor women who died, but they will still be hurting.
