Sad Prediction: Luci's gonna die

In front of all Sinners it's just been proven Lucifer can't lift a finger against them, but even an arch angel like him can be killed with angelic weaponry which isn't impossible to get a hold of. After Vox's rebellion fails or crumbles, sinners might decide that rather than reflect and take responsibility, they'd rather just shunt blame ultimately onto Lucifer, hold him down, and publicly execute him.

No doubt it would leave Charlie in a very dark place and seriously reconsidering redemption.
