Essentially, evil is a lack of goodness. Moral evil is not a physical thing; it is a lack or privation of a good thing. Moral evil is wrong done to others, and it can exist even when unaccompanied by external action. Murder is an evil action, but it has its start with the moral evil of hatred in the heart. (Matthew 5: 21-22). Committing adultery is evil, but so is the moral evil of lust in the heart. (Matthew 5:27-28). So to answer your question, based upon what the Bible says, there is more evil than good in the world. Of course if folks don't care about what the Bible says then my answer amount's to a spit in the river. :)
