God has created the spirit soul, God has created all the species of life, God has created the laws of nature and the reactions, but because we have free will, man is the cause of evil. God simply gives. He is the cause that facilitates us to choose either good or evil. There is no darkness in the sun. If you look towards God, you will see there is only light. However, if you look away from God, then you are going to see darkness caused by your own shadow. Man creates evil, and evil creates sufferings.
