You're making the assumption that the leaks don't make the US troops more likely to be killed. There certainly have been plenty of troops killed since July, and the leaks contained information other than just the names of informants that can put our troops at risk. I would love to see fewer people getting killed in these wars on all sides. I don't see how the leak helps that goal. Public opinion is decidedly against the war already, this doesn't change that situation. But the leaks put the troops in more danger, the informants/translators in more danger, and the result of that is more violence that leads to civilian deaths as a side effect. The more combat there is, the more civilians get killed.
