I think it may be something along the lines of past demons. Like, some past abuse or something. When Morgan sings, "I've laid to rest the demons / STILL, I'D LOVE TO WATCH YOU DIE!" That could be like, they've moved on but the resentment for the abuser is still there. She's laid the demons in her mind to rest but she's still feeling resentment toward the abuser. Hehe, that's just me.
