It's sick all the way around, but I wonder if the girl might have done something else to get attention besides dress older than she is. These young girls idolize people older than them on tv/magazines who set a bad example. I remember seeing video footage a few years ago of one of these "idols" pole dancing on top of an ice cream truck on an awards show, so there's a chance the little girl didn't realize such behavior was wrong.
That being said, the older boys should be ashamed of themselves for taking advantage of someone so young. You can blame the parents as much as you want, but no one forced those boys to rape her.
