(defun rs-gnus-summary-down-thread-max (&optional back)
  "Go to the lastest article in the current thread and show article.
With prefix, go up BACK articles from the lastest."
  (interactive "P")
  (gnus-summary-show-thread)
  (while (/= 1 (gnus-summary-down-thread 1))
    t)
  (gnus-message 7 "End of thread reached.")
  (when back
    (gnus-summary-up-thread back)
    (gnus-message 7 "Went back %d articles." back))
  (gnus-summary-show-article))

--8<---------------cut here---------------end--------------->8---

If the thread is hidden, an endless loop happens. Therefore i have added
(gnus-summary-show-thread) to show the thread first.
