So what, CJ 'prefers' it, but what should we do with the rest of the body then? If you know a foolproof way to let Mr. Aki vanish after we removed his hand, that's okay.
Space doesn't like this more bloody part of the job and would 'prefer': Take hand plus rest of the body to CJ, get the money and don't ask about, what CJ do with Aki afterwards. If CJ tells us, we get less money for the whole body, we can still cut of Aki's arm right infront of CJ.
