Did His Holiness Pope John XXIII, with his last words, wish to stop the Council that was in progress? That is what some of his friends like Jean Guitton have docuмented: "That Pope John XXIII wanted to close the Council after its first session was affirmed by John Cardinal Heenan of England (see source in linked post) and by Catholic philosopher Jean Guitton the only lay peritus at Vatican II." From St. Benedict's Centre https://catholicism.org/last-words-of-john-xxiii-stop-the-council.html

"Regarding the changes since Vatican II, Professor James Daly wrote:

It is one thing to pull off a revolution, quite another to do so and then have the gall to pretend that nothing “substantial” has been changed. It is not enough for our liturgical Robespierres to win; they must go on to claim that they never used the guillotine.[1]

Revolution was apparent very early on.  According to Anne Muggeridge (the daughter-in-law of the famous British Catholic convert and journalist Malcolm Muggeridge), John Cardinal Heenan of Westminster reported that when, during the rebellious first session of the Council, Pope John XXIII realized that the papacy had lost control of the process, he attempted to organize a group of bishops to try to force it to an end. But before the second session of the Council could open, Pope John XXIII died. His last words on his deathbed, as reported by Jean Guitton, the only Catholic layman to serve as a peritus at the Council, were: "Stop the Council; stop the Council."

Also, "Before the end of Vatican II, in February 1965, someone announced to Padre Pio that soon he would have to celebrate the Mass according to a new rite, in the vernacular, which had been devised by a conciliar liturgical commission. Immediately, even before seeing the text, he wrote to Paul VI to ask him to be dispensed from the liturgical experiment, and to be able to continue to celebrate the Mass of St. Pius V. When Cardinal Bacci came to see him in order to bring the authorization, Padre Pio let a complaint escape in the presence of the Pope's messenger: "For pity sake, end the Council quickly."

Vatican II: “the Council that has brought forth discord, disunity, and the loss of souls”
"I repeat, My children, as I have told you in the past, that the great Council of Vatican II was manipulated by satan. He sat there among you and he worked you like a chessboard.
  "What can you do now to recover? It is simple, My children: turn back and start over with the foundation given to you. You must bring respect back to your priesthood. You must bring respect back to your Holy Father...!" - Our Lady of the Roses, May 15, 1976"

The Pope must have seen a nightmare vision of the terrible future that would be unleashed upon the world after Vatican II. Thoughts?

Why would the Pope need to gather a group of bishops to bring the Council to a close?  He could have instantly dissolved it.

Unless he knew and the cardinals knew he wasn't the pope.

Read what he did to Abp. L and the group he headed. That should answer your question.
