Taken to an extreme, dishonoring of parents leads to anarchy, first in the family and then in society, as the decay of this basic component spreads. Eventually, a person will expend much, if not most, of his energies just surviving, effectively destroying the development of spiritual, creative, and intellectual qualities essential to his and society's well-being.
Not honoring parents also causes immaturity. Because children do not respect their parents' advice, they grow up missing the significance of much they encounter, and so wisdom comes to them very slowly. In some cases, they may never learn wisdom. Lack of honor manifests itself in self-willed and self-indulgent people who seem to simmer just beneath the point of rebellion. Their motto in life becomes, "Just do it." So they condemn themselves to learning the lessons of life through hard experience, which may be a good teacher, but a painful one.
