What gives the human beings the ability to decide what is right and wrong? I get told that murder is WRONG, Violence and war is WRONG, happiness is RIGHT!, but how can we tell. Right and wrong does not exist unless you believe in a superior being of all knowing that decides for us. Right and wrong is red and blue to most people, but when it comes to morality, I'm colorblind. I've given this alot of thought and some of it is still blurry in my mind but so far I've basically tossed out my pre-programmed bias about right and wrong and decided to look at it from a....universal angle.
Remember the questions like "If a tree falls in the forest and nobody is around to hear it, does it still make a sound?". I see a similarity with questions like this, and morality itself. If humans did not exist in the world at all, where human opinions never existed at all, could you still say there is right and wrong?. I believe human beings just chose to take on the role themselves to decide for the rest of us what is acceptable which therefor, is only an OPINION, a preception. This is something we are not qualified to do, just look at how it turned out. "God" the provider of what is right, is also one of the LEADING CAUSES OF DEATH throughout history(while saying killing is wrong).
The most obvious example of this whole idea is Nazi Germany and the holocaust. By todays standards, the holocaust was horrible and wrong and should have never of happened. Now looking at it from a nazi's point of few, it is the right thing to do. The only thing we have here are two conflicting OPINIONS, and the amount of people believing one thing over the other does not prove anything. If Germany had won the war and taken over the world, the vast majority of people would be Nazi's right now and it would be generally accepted that the holocaust was an achievement. Like I say, there is nothing out there(in my belief) that can tell me which one of these two opinions is right and which is wrong with concrete TRUTH. The holocaust is not right or wrong, it just simply....is as it is.
It's been said to me that humans were designed(the god thing) with a sense of right and wrong pre-programmed into us which explains why we have decided on what is acceptable or not. I sort of came up with my own theory to this. I believe it is the selfishness of human nature that has decided what is right and wrong and has passed it down the genes throughout evolution. What I mean by selfishness is, ideas that benefit humans, for example, Murder is wrong because it kills off other humans, and humans have to live co-operatively to survive. Murder is counter productive/survival and therefor been labelled WRONG. These things that are "wrong" are all things that seem to be counter-productive to human evolution. That is where I believe our conception of morality has come from.
