I would certainly be a lot more angry at the person who molested my child, than at the people who saw pictures of it afterwards. Their act of seeing pictures makes my child no more or less molested , in fact it is not possible for it to have any additional effect on the child that was not caused already by the molester taking the pictures/videos and releasing them to the internet in the first place, unless the child takes an interest in being notified every time someone downloads a picture or video of them.
