Well, that too, but I was referring to the fact that God commanded the Israelites not to take vengeance on the sons for the fathers' crimes, but he himself reserves the right to do so to the third or fourth generation -- or indefinitely, if you count the Garden of Eden scenario, and why shouldn't we?
The Gan Eden story was the answer of the ancient Jew for the questions, "Why is life hard for man when he's God's special creation? Why are the fields so hard to cultivate? Why is childbirth so difficult? Why do we die?" The answer was, "Because your first parents did something wrong, and naturally we should all have to pay the consequences." Killing the babies of the sinners in the Flood was a drop in the bucket compared to the billions who've suffered and died since Adam and Eve supposedly lived.
It's a Jewish joke that the Jews invented guilt. If that's true, then it's also the case that Christians have inherited this particular invention from the Jews.
