Children copy what they see, and that is one way how they learn, therefore if they see their elders, especially parents telling a lie, they will do the same, and if this is repeated again and again, they , as grown ups, will not feel guilty when lying. This type of lie is detrimental to their personality development. Lie will be a part of their personality; however, if they tell a lie just to protect them from punishment, then it will not be a common practice for them. Though, both are lies, but the former will have more negative impact on one's personality later in life.
