Noam Chomsky said this quote
“ I am not a committed pacifist. I would not hold that it is under all imaginable circumstances wrong to use violence, even though use of violence is in some sense unjust. I believe that one has to estimate relative justices. But the use of violence and the creation of some degree of injustice can only be justified on the basis of the claim and the assessment-which always ought to be undertaken very, very seriously and with a good deal of scepticism that this violence is being exercised because a more just result is going to be achieved. ”
