Did Elizabeth Swann kill Captain Jack Sparrow in Dead Mans Chest?
She didn’t actually kill him, but she set him up for death. The Kraken was right under them, after attacking them for a first time (they scared him away temporarily) and Gibbs, Will, and the rest of the crew were all in the escape boat, aside from Jack and Elizabeth. She pinned him up to the mast, and kissed him, while doing so, she cuffed him to the mast. She escaped, leaving Jack for dead. Jack got out of the handcuffs, but the Kraken was on top of the boat by then, mouth open and spewing nasty snot-like stuff on him. His hat pops out, and he puts it on, and gets eaten. It was very sad, really.
