According to Smrutis, the effect of the adharma done by a person attacks the doer slowly and cuts off the roots of the perpetrator. The punishment for the sins will fall on him, if not on his sons and if not on his grandsons. Thus a person's entire family is impacted adversely by the sins committed by a person and the perpetrator is bound to reap the fruit of his sins.
