There is a lot of things people can be inspired by to commit horrible acts of violence. A decade ago it was GTA and video games. A decade more it was rap. Before that all the classic 90s action films. What I would be worried about is the social environment which had a person that was able to consider murdering 10 people. The classical profile would be a person with no social support, no attachment to their near environment, and borderline personality disorder. Looking at the details about the attack, it was a high school teen who moved to Toronto with no attachment to the new home, was a social outcast at the bottom of their perceived social ladder, and suffered from a personality disorder. While its only a very small portion of such people that are able to consider becoming a mass murdered, much of the risk factors were preventable. As a society we are much better off if we focused on fixing the risk factors than what ever is an currently popular inspiration once a person has decided that it is okey to kill an other human being.
