The philosophy of good & evil in humanity

After reading the article "The philosophy of good and evil in humanity" i have learned about the two opposing sides, good and evil. The article has explained to me that throughout history people have always wondered why their were two sides and where evil originated from. Philosophers think that evil should remain in society otherwise their will be no good. Their has to be two sides to balance things out. The main focus of the article is whether evil should remain in the world or should be banished. I personally believe that evil should not remain so the world would be a much happier place to live in. Their would be no crime, abuse, or backstabbing in this world. People would happily live their lives, go home to their family every night, and watch a movie. The world would be much easier to handle. Yes, good has to come in to stop evil, but without evil there would be no problems in the first place. The article has made me come up to many conclusions.
