The Slenderman is arguably the most famous and successful Creepypasta of all time. But in recent years, Slenderman has been blamed for several violent incidents, including multiple attempted murders. The most famous of these murder attempts occured in Wakausha, Wisconson, when two 12-year-old girls stabbed their best friend 19 times and left her for dead. What caused this horrifying attack? Is there something insidious about Slenderman that inspires murder? Does dark or graphic media cause violence? Is anyone to blame for all of this?
