If I were in that situation, I would hand over Luffy as well.

Aaaaaaaye

Aye; let him be their problem for a few minutes (until he manages to blow up what's left of their ship from the inside).

That plan would last right up until Cory remembered his loyalty flaw.
Unless Luke voted Aye, too.

Well, it does mean trouble for the entire crew if he doesn't. Granted, they normally don't have to run from trouble, but they need a cook here.

Well, if they destroy the Baratie and every other ship in the area, the cook will have no choice but to sign up with them. And if Cory makes it clear that the cook has to be as loyal as he is or else...
Instant cook. Just add violence.

and Luffy would loose his martial artist levels since that would cause him to no longer be good aligned. I think they're willing to put up with a bit of inconvenience to keep their cheesy build intact

Story time today is about handing your pirate captain over so you don't get blamed! Aaaaand go! I am expecting some great stories!

I got nothing

Does it still count if I was a plant?
