Charlie died the chivalrous death upon the island he was meant to experience, and it is Jin that lived on remembering everything that happened on Eden Island. Sadly the information drove him insane, and he was placed in an institution.

As sad a fate as this may be, it happened for a reason, and it seems you have chosen wisely in the case of this final file.
