Evil is God, God created the evil just as he created the good. Its a tool used to teach. This is all a giant play, written and directed by the one. You wouldn't want to watch the same happy movie over and over again would you? This is all a giant movie for entertainment, people just get lost in the illusions some times. If you can step back and not be so tied into a character in the movie, and watch the movie as a whole from a step back, you begin to see how epic and amazing this movie is. Its all for entertainment, with the purpose to teach...

Sometimes I feel its more a video game than a play, but thats for another discussion
