Even though we never got Doffy's flashback or even finished the arc, I still disagree.
From what we know so far, Doflamingo started becoming evil after he lost his mother. In my opinion, that's not a very
powerful reason. That type of reasoning is generic since been done many times in fiction. Hell, Orochimaru and Nagato turned evil because of the same exact reason.
I like Arlong's physcological process because it was different. At first, Arlong was just the average typical Fishman who hated humans simply because of all the discrimination that the race has been through. But what really pushed Arlong into the dark side was the fact that Fisher Tiger demanded that Arlong try to cooperate with humans right before Fisher Tiger died of blood loss. FT could have survived, but he still refused to intake a humans blood. At the end, Fisher Tiger could not accept humans. But he still demanded that the Fishman try and make peace with the humans. Arlong could not accept that, which was what drove Arlong mad for revenge. And then later on, Arlong hit absolute rock bottom when even Jinbe advocated to follow Fisher Tiger's final orders.
His trauma is just so complex. Much deeper than simply losing a parent. His trauma is also
ironic because just when the Fishman Pirates thought that there was hope of their race to be able to coincide with humans (the Koala experience), humans end up pissing them off even more. The use of irony was great with Fishman, it's basically Togashi level in use of irony.
Meruem thought that he could change the world with all these specifications and borders etc., but Netero knew deep down that this young ant knows absolutely nothing of the world.
And I highly doubt that we will see Doffy's flashback in Dressrosa. Arlong is the only villain to ever get a real backstory, and Oda waited all the way to Fishman Island to finally reveal it.
& you get a bigger feeling of danger from him than Croc.
did not see this comment above sorry
anyways, I disagree.
Doflamingo nearly killed Law, who is only a supporting character. Croc nearly killed the main character twice. See the weight difference? Also, Doflamingo sets up a birdcage on the island, big whoop. Crocodile engulfed an entire CONTINENT in drought using his devil fruit.
