I agree that the image that the parents give to their children is essential.Strong role models are crucial to young people in a world increasingly settling into a morass of decay. I would argue that the lack of proper role models both male and female are a big part of the reason why civilization is starting to backslide. And I never said that they have to come from the "elite" classes; decent parents would do for a start.
Good education also.
But the children do not have to take the personality of their parents as a model.
The children have their own personality, not that of their parents.
For the eventual deviations, later there are the laws of justice.
