There is a great foreword to the Director's Cut edition of the JTHM collection (Jhonen Vasquez's first comic, Johnny the Homicidal Maniac), that discusses the importance of having orcs to stab, which I think is a very important point to make:

Quote
A girl I dated once said to me, "You only feel when you bleed." This must give you the impression that I was dating an Art School-Vampire. She was more like an acid-washed Molly Ringwald, but that doesn't matter. I fell in total lust with this woman because she told me what I had been thinking my entire life. Pain is food. A food that is essential to the growth of one's soul.

Let's talk about violence, shall we? Violence in the media is an easy target. "If we get rid of all the violent movies, television shows, and comic books, the world will be Utopian!" An easily believable answer. Just ask your mom.

Jhonen Vasquez has touched something important here. There's a little monster inside all of us, a little wolf-faced monkey that needs to be satiated. As people, we mustn't ignore that monster. If we do, we cheat ourselves. We deny an emotion, a feeling.

Think of someone who pissed you off. Some yutz who cut you off in traffic; a prick-ass Kinko's employee who took three hours to copy your resume; the big bully who spit in your face when you were eight. Now, in your head, relive that moment. This time, however, don't just stand there and take it. This time you've got a knife. Pull it out from behind your back and watch the status flip-flop. Suddenly, Mr. Kinko isn't so cocky. The playground bully is crying for his mother. Smell their fear.

Then, kill them. Kill them like you see in the movies. Make it as horrible as possible. Release that monster and stab that knife deep into their face.

As humans, we are taught to forget that we are animals. Animals kill to survive and it's just as natural for us. To deny nature is to deny life. Now that you've committed murder in your dream world, relax. Take a deep breath, give your monster a high five, and put him away. You've just used an evil fantasy to keep you civilized and sane.

Some may call this irresponsible advice. They kid themselves that their monster doesn't exist. And when a person lies to themselves, there is less chance for spiritual growth. More than likely, their monster will step out of the Dreamwold and into the Realworld. That's how a society gets messy. Lots of neglected, hungry monsters.

Johnny the Homicidal Maniac gives our monsters something to chew on. It's pain-food that wears its teeth down. Johnny represents Jhonen Vasquez's monster. Vasquez, and his fans, are all the stronger because of him.
