In Pirates of the Caribbean: At World's End, during the scene where the Brethren Court meets to decide to fight against the East India Company (Lord Beckett), we hear this conversation between Jack and the "Keeper of the Code" (who is also his father)
"What? You've seen it all, done it all. You survived. That’s the trick, isn’t it? To survive?"
"It’s not just about living forever, Jackie. The trick is living with yourself forever."
Does it mean that he is immortal? There are some conversation also in next movie (On Stranger Tides), however I am not able to find conversation.
I am looking for reference if he is immortal or not. And if this conversation is not about immoratility then what is it about?
