The track seems menacing at first with loud and angry sounding trumpets and various other loud musical instruments. Nearing to the middle the song quietens down for a moment but gradually increases to the same loud and fearsome music. However, coming towards the end the music calms down and becomes alot quieter and peaceful.

You can even hear the music representing the hint of good in him. Showing the inner conflict and pain, as it goes from pure anger, hatred and destruction to peaceful but still confused and afraid, just like Kylo Ren.
