Including the 500 hostage soldiers he killed for being weak so that the pirates who took them hostage couldn't use them anymore?

They are quite useful, doesn't mean we can take one with us.

I gave a message for Aokiji to give Straw-Hat if he saw him again. After Alabasta the brass got on my case for taking off from Loguetown against orders so they didn't let me keep tailing Straw-Hat so I told Admiral Aokiji if he saw you guys at some point... well never mind. Point is, according to Roronoa he didn't do it. So maybe I just won't keep him informed this time around.
