The reason China and Korea pointed their fingers on Japan is not because they think "the son should inherit the father's guilt or shame" but because this son did not really think what his father did is wrong for a very long time, in fact, this son teach his son/daughter that their grandpa did not do the guilty thing that actually did with irrefutable evidences, the son think and teach his son/daughter that some victims are voluntary to become victims. The son also put his father to shrine and think/treat his father as a hero. If you are one of victims' family member, what do you think about this son? Will you like him?
