The Demons of the Old Testament

The gods of the Old Testament were real. They had some authority in some areas and then Christ's death. I think releases it maybe back to human beings being in control of each other. Even the demons in the New Testament say, have you come? Is this our time? Jesus' first coming was his second coming. There's still this remnant of evil. And then that's where the debate is of how much power, where are they locked up or they released? What is a demon? What isn't a demon? How much can we be influenced?
