I discovered that there is a predominant characteristic with the forces of evil that is different from God’s people: Evildoers fight and are always seeking to dominate and gain the topmost power at all cost, while Godly people are peaceful, kind and not selfish; they think of serving others.
There was a time when mankind did not know evil; they did not know the difference between good and evil. God knew the differences, so He cautioned Adam as it is written in Genesis 2:16, God warned him.
