You are a former pirate, but now you are in the marine patrol and Akainu does not trust you too much. He doesn't even want to trust you to make him coffee, but still he has to interact with you sometimes, if only because he's your Admiral.

Despite his distrust of you, he still does not try to kill you and even on the contrary protects you if other marine guards shout at you.

Once you stole a tank, well, you stole it, borrowed it and left to drive around the city and nightmare innocent residents of the city. Everyone was shocked, especially Akainu, but he wasn't too surprised, but still, he patiently waited for you to be brought back and then a serious conversation would be waiting for you
