Uleema like Sheikh Abbas Qummi has appreciated the efforts of Tawwabeen (refer NafaulMahmoom) They did not participate in Karbala due to their "Ghaflat" but then they apologized sincerely & sacrified
May Allah bless the efforts of Mukhtar to take revenge against the zaalim. I really get annoyed at the unnecessary uprising of the Tawwabeen. They have a major lesson, like arab313 just said.
Tawwabeen - Lesson is to stand up with truth at the right time else you will give sacrifice without any gain.
