Not everyone. Usopp just wants to be a brave warrior. Nami wants to make a map of the world, but has said it more as a personal ambition. Sanji wants to find the All Blue so he gets the opportunity to cook with all kinds of fish. Brook just wants to see Laboon again. Robin wants to discover the True History.
My point exactly. They all have stated ambitions.
–- Update From New Post Merge ---
This may be true in a sense ,but have you ever considered he has never really had a chance to express such a dream? It's been pure chaos in this manga since Jinbe's introduction. But to say he doesn't have a dream is faulty since he's never had a chance to say anything on the subject ,this imo is Jinbe's biggest pro he's still a blank canvas,he's been so caught up in his Countries affairs , he's never done anything for himself just think about it:
He joined the Sun Pirates for Tiger
He joined the Shichibukai for Otohime & Arlong in a sense
He Left the Shichibukai for Ace & WhitebeardThe only time Ive ever seen him do something for himself is when he saved Luffy even this is selfless, though he initially rejected Ace's request. Jinbe maybe the least selfish person in all of One Piece but to say he doesn't have a dream is an assumption at best[[even Hachi has a dream]] but only time will tell.
That's very true, I never realized they've been going at it non-stop since Impel Down (sans time skip). I would love for Jinbe to join the crew, don't get me wrong, but I'm still slightly skeptical on his chances of joining.
edit ohhhh automerge is nifty
