I believe Arlong might be the "James Earl Ray" we are looking for. Fisher Tiger died because of an act of compassion towards humans (i.e. returning Koala to her home-town). Instead of helping to bridge the gap between Fishmen and humans, his actions were met with suspicion, fear, and ultimately betrayal. Tiger's actions coincided with Queen Otohime's doctrine of Human-Fishman integration/interaction. Tiger even validated Otohime's beliefs on his deathbed, and told his crew mates to support them as well. Perhaps Arlong, in his rage and grief over the Boss's death, blamed Otohime for negatively influencing Tiger's mindset and bringing about his end. After all, we know how much Arlong hated the idea of "Pew-mans" and Fishmen living in harmony with one another; he thinks we're an inferior race of bottom feeders who should be punished and ruled over. Maybe Arlong was even forced to do it. As of Chapter 623, Borsalino said he would be taking Arlong somewhere. Maybe Borsalino and/or the World Government had their own agenda for taking out the Queen of Fishman Island, and they used Arlong as the tool. It would also certainly explain why Jinbe "unleashed" him into the East Blue. It could have been to protect Arlong from the wrath of Fishman Island, or else banish him from Ryugu Kingdom as a result of his actions. But hey, that's my theory anyway. Jihahaha!
