God is dead. God remains dead. And we have killed him. How shall we comfort ourselves, the murderers of all murderers? What was holiest and mightiest of all that the world has yet owned has bled to death under our knives: who will wipe this blood off us? What water is there for us to clean ourselves? What festivals of atonement, what sacred games shall we have to invent? Is not the greatness of this deed too great for us? Must we ourselves not become gods simply to appear worthy of it?
If you take way the creator of a system of rules and guidance does that system also get taken away? I say no. We all came from somewhere. That is obvious. But just because you take away the bible does not mean I still don't remember what it did to me. Or maybe that is not what he meant? Maybe He was asking what would happen if you not only killed your god, but removed any trace he ever existed? For example if you never knew a God. If there was never a preacher or a parent or teacher who taught you the ins and out of this societies rights and wrongs. Would you know the concept? Could you know the concept?
Consider a family of anarchy. The one role the parents and your teachers played in your life was to to feed you and teach you facts. Your learning was restricted to only that necessary for you to get a job and feed yourself. It is only you and your parents in this school of life and there is no one to taunt you and yo get no TV. You grow up isolated and only know how to make money, put a roof over your head, hygiene, and how to feed and cloth yourself. Wait I will create something better for you. You grow up isolated, you only know of money and what it is used for, your parents are rich so you need no job, you know of hygiene, you know how to cloth yourself, and you are trained in realistate so you know how to put a roof over your head, you also where taught deductive logic. Ohh and in my world a kid will grow up in the environment and not be insane when he leave. But really I guess that does not matter.
So day one you leave the house and walk out into the city for the first time. Suddenly in front of you a homeless man appears. In my world things just appear like that so shut up and pay attention. Right after that Three thugs appear in front of him and proceed to beat him senseless.
What do you think you would do? You have never seen violence. No one told you that is was wrong to beat random people up. You saw nothing of news and TV. You where very deprived. All you have is a brain full of ways to keep yourself alive and a scene in front of you of a man getting his ass whooped. You are no coward as you have never seen anything to give you a reason to be. You are not timid. Tell me what happens. Then I will tell you what I think.
