Hody killed the suspected murderer on accusations that he was human and had a gun. Since the guy is dead, you really can't question him if he truly killed her. Of course this is a setup that the no-name human is being used as a scapegoat. Hody has done everything to further his agenda, and he does not care about hurting other Fishmen.
I thought Sanji was a bit overboard this episode. He has never wished anyone to kill themselves. Is that a filler? Since it seems so out of place.
Well, now it's time for Luffy and crew to take action and destroy Fishman Island.
