Can you imagine if one of our sons deliberately went against us on a serious issue. Yes it may well afect our relationship in the coming years with him but it certainly would not mean that we have it in for his ancesters 6000 years down the line.
The whole account is a joke. Notice how the WT adds things that are not in the account. They decide it is God's heavenly woman refered to. But it does not read that way. Also where does it say the sead would take thousands of years to put things right again.
