Who killed the Kraken in Pirates of the Caribbean?

As an expert in the field of film studies, I have a comprehensive understanding of the "Pirates of the Caribbean" franchise, which is a series of popular action-adventure fantasy films produced by Walt Disney Pictures. The series is known for its blend of swashbuckling action, supernatural elements, and historical fiction, set in a world where pirates, mythical creatures, and the British East India Company are central figures. The question you've asked pertains to a significant plot point in the third installment of the series, "Pirates of the Caribbean: At World's End." The Kraken, a mythical sea monster of colossal size and power, is a central antagonist in the film. It is a creature of the sea, controlled by the heart of Davy Jones, which in turn is controlled by Lord Cutler Beckett, the main antagonist of the film. In the narrative of the film, the Kraken is sent to hunt down and destroy the pirates who stand against Beckett's plans for control over the seas. The creature is depicted as an unstoppable force, capable of dragging entire ships and their crews down into the ocean depths. However, the Kraken meets its end at the hands of Davy Jones, who is portrayed by the actor Bill Nighy. The scene in question is a pivotal moment that reveals the true extent of Beckett's control over Davy Jones and, by extension, the Kraken. Beckett, played by Tom Hollander, orders Jones to kill the Kraken to demonstrate his power and to eliminate a potential threat to his plans. This act is a tragic one for Jones, as he has a complex relationship with the creature, which is tied to his own tragic backstory. When the moment of the Kraken's demise is shown, it is a poignant scene where Jones, despite his hardened exterior, is visibly affected by the death of the creature. He retreats to his quarters and plays a sorrowful tune on his pipe organ, reflecting the depth of his character and the tragic nature of his situation. The killing of the Kraken is not just a plot device but serves to highlight the themes of control, loyalty, and the consequences of power within the film. It also sets the stage for the climactic battle and the ultimate resolution of the story arc involving Jones, Beckett, and the pirates. Now, let's proceed with the translation of the above explanation into Chinese.

At World's End. The Kraken is briefly seen in Pirates of the Caribbean: At World's End, wherein it has been killed by Davy Jones under the order of Lord Cutler Beckett. When reminded of this killing, Davy Jones appears distraught and plays sad music on his pipe organ.
