Many have the wrong impression of Jesus. They do not realize that much of what he said was not gentle but strong. However, all of his words were constructive. If he punished with the tongue, the purpose was to awaken the individual to the wrong. Jesus gave logic, explaining what was wrong and what was right.
Accumulative guilt is passed down until the time comes for an explosion that cleans the slate.
When the judgment is due, it weighs heavily on those then living. However, when the responsible individuals come up in the resurrection, they will be held accountable for what they did willfully. Hence having the judgment at the end of the Gospel and Jewish ages does not mean those of other generations escape. They may escape judgment in the present life but not in the next. “Some men’s sins are open beforehand, going before to judgment; and some men[‘s sins] … follow after [with judgment occurring in the Kingdom]” (1 Tim. 5:24).
