In the beginning, Bootstrap Bill (Stellan Skargard) establishes himself as a hero by essentially sacrificing himself for Jack Sparrow (Johnny Depp). Bill “stood up for [Jack and] everything went wrong after that”. He would rather be killed than betray his captain.
Bootstrap Bill is eternally dedicated to his son, Will Turner (Orlando Bloom). He would do anything to save his child.
When William challenges Davy Jones (Bill Nighy), he is ready to sacrifice his soul for “the key”. However, Bill is not ready to let his son go. He would rather sacrifice “eternity on [that] ship” than let his son lose. Bill is all about self-sacrifice to help those he cares about.
Jack also made a sacrifice for the Black Pearl. Davy Jones “raised the boat from the depths for [him]”. Jack sacrificed his “soul” for the sake of the ship he loves dearly.
Jack even sacrifices his hat to save himself, his crew, and the Black Pearl. Every sacrifice he makes for the ship is actually selfish.
Jack is also supposed to be a sacrifice to the island people to release their god. However, he is not actually a god, and only uses the façade of being a god to his advantage (not even the advantage of his crew or the ship). These expenses do not work towards the greater good.
Later, Elizabeth (Keira Knightley) almost gives up that she is a woman on a man’s ship to get the crew to go to Torguta. Her sacrifices does not actually affect her negatively; she gets away safely. She tries whatever means necessary to save Will Turner.
Also, why would the Bible be brought up in this movie? Because a selfless sacrifice (like what Jesus made) is supposed to save everyone’s souls and lives. Therefore, this reference represents yet another example of how self-sacrifice helps people.
When sacrifice is made in support of other people, it is beneficial and (in a way) acceptable. Sacrifice does not always mean doing what is right, but, in this movie, sacrifice includes committing oneself to a cause
