Evil which is turned to good is greater good

Arvei Nachal(#23): G‑d created man for His honor and in order that there be reward and punishment in this world. This is the result of man having free‑will to do good or evil. However it is impossible to have free‑will unless man himself is a combination of good and evil. It is because of this man has the ability to turn from evil. Therefore when the good overcomes the evil – the evil turns to good and the reward is very great. The Zohar (2:184a) states that good exists only in turning from evil. In other words, even thought the good is inherently good, however the evil which is turned to good has a much higher quality. This is stated in Bereishis Rabbah (9:5): “very good” is referring to death. In other words that evil that is turned to good is very good and it is called “very good”. Consequently this is what G‑d wanted in the creation of man. It is impossible to accomplish this unless man is a combination of good and evil.
