Akainu IS just doing his job.
He's one of the few Marines that seems to know what duty means. He gets the job done. Of course this means following orders blindly and if you're working for a 'crooked' cause then…
But honestly? Who was the one in Ohara that knew 'No survivors' REALLY MEANT 'No survivors'.
Who was the ONE Marine that said, "Fuck honor! This is my damn job and I'm going to do it!", when it came to Ace.
As a villain, I respect that and I don't necessarily think that makes him despicable. I'm interested in what makes him tick, what crawled up his ass and blinded him to any trace of pity.
The problem is, he's working for what appears to be a dangerous cause.
I really enjoy how Oda's crafted the Marines. Their loyalties are all OVER the place which is realistic as HELL.
For me, the Marine I see as the biggest wild card is Kizaru.
I simply CANNOT gauge the guy.
He's vicious and dedicated to his job like Akainu but just something about him that isn't as mechnically inclined towards blindly following orders to the T as Akainu does. I'm interested to see where his loyalties will wind up at the end of all this.
What were we talking about?
Oh yeah, Arlong.
I always had the impression that he just enjoys killing and uses his job as an excuse to do so like Lucci or Shiryu
