Gosh, that's a bit hard to say. It depends if you're frightened if that child might view much violence or if you're frightened if the kid would get scared. Yes, it is quite violent, and it does include violence. But I really don't think that the violence part makes it a mature rated show, since we all know that kids at 11 years are all guilty for viewing at least something violent. Same for drugs, sooner or later they are going to hear it somewhere in life.
