Everything can be understood from the cross first. Acts 4 tells us that the cross was predestined, meaning those who murdered Jesus were predetermined by God as the villains of the story. In 1 Corinthians 2:8 it says if they knew they wouldn't have crucified Him, and therefore nobody would be saved. Those who God doesn't save have a purpose as the villains to the story. We don't know who that is, because anyone can turn a round at any point, but everything has a purpose -- both the wicked and the saved.
