Do violent TV shows and video games actually make kids more violent? Maybe. But if they do, then you're going to have to lock up Shakespeare with a MA-17+ rating, too, because Macbeth's body count is out of control. And it's not just aliens or zombies being brutally slain: it's women and kids, too. As with all of Shakespeare's tragedies, Macbeth piles on the violence. Just as we ask whether it's necessary or gratuitous in the latest James Bond movie, we can ask the same thing here: is there a good reason for all the violence, or did people in the seventeenth century like to watch blood being spilled just as much as we do?
The reason that Macbeth's violence is inexcusable is because it doesn't play by the established rules. In Macbeth, organized violence is sport, and individual violence is uncivilized.
Throughout Macbeth violence and cruelty are associated with masculinity.
