As William Blake would have put it, these two concepts cannot live without each other. How could we know what was right if there was no wrong? What would be the reference point? My favorite line of his is,
"You never know what's enough until you know what's too much."
It's like love and hate. If Adam and Eve had stayed in the Garden of Eden and never known loss and betrayal and hate, humans would not have made much progress (if you want to call it that). For me, this is the beauty of what happens in 2001: A Space Odyssey.
When the monkey learns that he can use tools to kill other monkeys, he has essentially eaten the forbidden fruit from the Tree of the Knowledge of Good and Evil. Nothing he had ever done in his little monkey life had ever made him feel true guilt, until he used a club to beat another monkey to death.
Here you have the beginning of Man and all the baggage that goes therewith. Including this language we use here to argue with each other.
