Why did God create bad when everyone wants good alone?

The good is the Satvam quality. The bad is Rajas and Tamas qualities. These three fundamental qualities constitute the entire creation, which is the game of the Lord. The bat, ball and net are the three means of the game. You beat the ball with the bat. But in beating the ball you are not angry with the ball nor do you hate the ball. You beat the ball as part of the game. Similarly the bad should be destroyed and the good must be established as in the game. But you need not be furious with the ball or hate the ball. Without the ball, the game of beating the ball cannot take place. Similarly the game cannot start without the bat. Thus good and bad are equally instrumental in the game. The actor, who played the role of hero and the actor who played the role of villain are equally important and both are paid well. Rama killed Ravana and Krishna killed Shishupala. The Lord killed them peacefully without any hatred towards them. He knows that He is playing the game. He beats the ball but without any anger or hatred. When one sees all the three qualities with an equal view without any tension, he becomes a follower of Datta. Datta means the equality in the three qualities. Brahma is Rajas. Vishnu is Satvam and Shiva is Tamas. All the three forms are equal and constitute the whole game. Thus the Lord destroys injustice and establishes justice without any tension or hatred in His heart. You want the villain in the movie. You want salt and sourness in the meals. But you don’t want to see bad in the creation! The creation is a movie for the Lord as said in the Veda (Sa Ikshata, Saakshee Chetaa). The creation is the full meal of the Lord as said in the Brahma Sutras (Attaa Charachara Grahanat). If you are served with meals containing only sweet items or you watch a movie without a villain, then you will not put this question.
