Vast majority of the injured and dead have been Hezbollah members. And the civilians have been their relatives who picked up Hezbollah pagers - they did not deserve an explosion in their face, but it's not like these pagers had been indiscriminately sold to civilians. They should blame their relatives for putting them in danger.
By the way, the two 12 year old boys mentioned in the AP piece were both members of Nasrallahjugend (real name Hezbollah Scouts), their youth division. So while the targets were their terrorist fathers, they were not exactly uninvolved civilians either.
