I was an angry young man ...
I was an angry, young man. By age 15, I started recognizing that. By age 24, I had eliminated every ounce of it.
I think everyone is violent. The question is, how "content" are we? Being "content" mitigates and even eliminates violent tendencies, at least that has been my experience both first-hand and what I see first-hand.
A lot of people turn to violence when they cannot find peace with things. They might think it's about "resolution," but it's actually about making your peace with things. If there is any, common denominator among all spiritual teachings and religions, it's that.
So the real question in life is, what makes you content? What keeps you from dealing with things in violent ways? If you have trouble finding it, then -- as much as it sounds cliche -- sometimes finding religion is for you. For others, it depends on what makes you content.
But even beyond that. Ask yourself if you will still be content if you lose what makes you content? Now that's where I really start to question people. As much as people say religion causes wars, the true, spiritual quest that most undertake actually doesn't, and people who are spiritual do find contentment in most situations (assuming they don't blame God, which many do, and then leave).
My life with my wife makes me content. If I lost my wife, would I still be content? I think so. I'd find a way. I learned that nothing is for certain in this world. So arguing about money, worrying about everything that could happen, and otherwise thinking I cannot survive if my world was turned upside down, is definitely things I have left in the past.
So the question is now to you. Do you have a good life? What do and don't you like about your life? What makes you content? What doesn't? How are you going to deal with it? Don't use violence as an escape. It's hardly healthy. If you are very content with your life, then a fantasy of violence could be an indicator of another issue.
As far as Fight Club, Hollywood is hardly life. Hollywood tends to over-simplify everything. It's not what it seems. Don't live in the movies, because in real life, they pretty much all have bad endings. I assume this is all your problem is, and it's nothing to be worried about -- unless, of course, you act upon it.
And then you'll find your not Edward in the end.
