Why? The work that the marines should be doing now...there are many things that you have to take care of. Don't know that Arlong has killed many people and destroyed many villages? Under his control, everyone was treated like a slave! And you didn't do a single thing about that!! And now you just want to find the treasure of one thief? Is this a real government?
Hopes for the future..? Yes. However, getting there with you...is not much different than being alone..! What good is the treasure if I'm alone? After sharing so much of our dreams. Instead of sacrificing them and leaving with you I would rather... HAVE NOTHING AT ALL!
