I’m no psychologist, but from what I’ve read it’s inherently damaging to be raised in a dysfunctional family, and that’s more likely to lead to another dysfunctional generation. People from supportive families may not naturally be the most empathetic, but they’re less likely to have issues with drugs, gambling, alcohol, violence, etc if I understand correctly.

When you’re impressed by those who have struggled out of dysfunction and became stellar people because/in spite of it, that could be selection bias.
