User blog comment:Samium/Buster Call on Enies Lobby (Aokiji's motive)/@comment-2226235-20160531061807

What do you mean? Aokiji's only involvement in the Buster Call was telling the Marines not to pursue the Straw Hats since it was already a defeat. The reason he spared her at Water 7 afterwards was because she had finally found a place where she belonged. He tried to have her killed before because he thought she hadn't changed and would just drift from group to group and abandon them as soon as she attracted too much trouble.
