The kids are not responsible for who their parents were or what evil their parents did.
The kids are only responsible for what THEY do on this planet.
Hopefully, their parents’ murderous deeds will inspire the kids to do great things to help the survivors and their families and people in Israel or where-ever, but the kids are NOT to blame for their parents.
You have to embrace the guilt so you can write books and documentaries about how guilty you feel.
