The Source of EVIL -Bible Truth

A Christadelphian Video: Description: Theodicy is the belief that GOD cannot create evil and therefore disasters and troubles in the world could not be from GOD. The words such as “satan” and “Lucifer” are interpreted as evil ones. Examination of the Bible reveals how these words are used. He goes through the history of the Jews and how many of them came from a polytheistic belief to a monotheistic belief. So is the Theodicy belief correct or is there another answer?
