Answer: The miseries and wickedness of humanity did not come from good, but good came out of wickedness and miseries. If it was not for wickedness and miseries and wrong we would not have appreciated what good and right means. It is these two opposite poles which make us distinguish between the two. If there had been just one thing, we would have called it goodness or wickedness, but it would have been just one. Calling it by two different names helps us to distinguish them.
