In Pirates of the Caribbean: The Curse of the Black Pearl, Will Turner finds out that Bootstrap Bill was tied to a cannon and dropped to the ocean floor, if not for the Aztec curse, killing him. This happened after the mutiny against Jack, led by Barbossa. So, Barbossa is responsible for the death of Will's father. But in Pirates: At World's End, during the Maelstrom battle, Will asks Barbossa "Hey, murderer of my father, you're a captain, right? So you can perform weddings, right? Would you like to wed Elizabeth and me, right here?"
Did he forget who was responsible for his father's death and subsequent enlistment to Davey Jones' crew?
