Oh, no disputing the Mullahs have been and will be brutal, like the Basij who just got a clear signal to break heads from Khamenei's foolish speech. The revolution was only a good thing in that it established a republic as a concept in the first place. The fall of the reactionary mullahs(which are not the only ones--Iran's most senior cleric, who fell from grace for criticizing Khomenei's policies, is on the side of the protesters; Khamenei in fact is not respected as a cleric and was given his position for keeping his nose nice and brown when Khomeini was alive) was implicit, eventually, in the revolution itself--the "supreme leader" is inherently at odds with the concept of a republic.
