He did not get off, this was just his delivery to the final court. Now he awaits trial for perhaps a decade or two, then comes his sentance. I imagine the lake of fire for him. Hopefully not too many have to burn along with the demons for eternity.
He will actually go face to face with the real God, see His mercy and righteousness, then see His Wrath for him.
Imagine his shock when he is sentenced to burn with Allah forever and never see the real God again.
