It sure seems that way. Nick Cohen on the Treachery of Julian Assange:

As soon as WikiLeaks received the State Department cables, Assange announced that the opponents of dictatorial regimes and movements were fair game. That the targets of the Taliban, for instance, were fighting a clerical-fascist force, which threatened every good liberal value, did not concern him. They had spoken to US diplomats. They had collaborated with the great Satan. Their safety was not his concern.

 

David Leigh and Luke Harding's history of WikiLeaks describes how journalists took Assange to Moro's, a classy Spanish restaurant in central London. A reporter worried that Assange would risk killing Afghans who had co-operated with American forces if he put US secrets online without taking the basic precaution of removing their names. "Well, they're informants," Assange replied. "So, if they get killed, they've got it coming to them. They deserve it." A silence fell on the table as the reporters realised that the man the gullible hailed as the pioneer of a new age of transparency was willing to hand death lists to psychopaths. They persuaded Assange to remove names before publishing the State Department Afghanistan cables. But Assange's disillusioned associates suggest that the failure to expose "informants" niggled in his mind.
