That's a good question. Nobody knows how to kill Jolly Roger. He could kill Davy Jones by stabbing the Heart of Davy Jones, but if he does, his heart must take its place in the Dead Man's Chest. But, since he's the undead skeleton, we don't know if Roger actually has a heart. Now that's what you'd call a complicated situation.
