All things in this world are in pairs—male and female; night and day; positive and negative particles, matter and anti-matter. Everything in this world joins its pair and fulfils its purpose. This is a clear proof of the fact that this universe is purposeful. In such a purposeful universe it is impossible for both the good deeds and the bad deeds performed in it to have the same final consequences. This would not be consistent with the image of the Creator presented by the universe.
