It is pity. Even the New Testament passages that predict the end of the age can be read and interpreted two ways. So it will be at the close of the age. It is interesting to note that several of his disciples were fishermen. But they were not sport fishermen.
Sport fishermen throw away everything except the most perfect specimens.
His disciples were commercial fishermen. And commercial fishermen always keep every fish they possibly can. So, that is how those disciples would have understood this parable. I believe, in the judgment at the end of the age, God and Jesus and their angels will rescue all they can. Christianity has more than one theology.
