You do realise that was the point of his character, right? You were never supposed to like him.
You complaining about him being evil for no reason is like me complaining about everyone else being "good" for no reason. Don't use double standards.
Using strength as an actual argument is incredibly flawed reasoning.
Alright, tell me why he was a "good" villain then? I mean at least try to use logic when saying my opinion is wrong. Just read my posts above if you want to know why Hody sucked as both a physical and intellectual villain. I mean the fact that he was willing to attack his own crew and fellow Fishmen only makes him less realistic. You'd have to be a complete idiot to follow this guy.
Going by that, a LOT of villain plans in One Piece would have fallen apart when you have powerhouses like the admirals, warlords and emperors.
Arlong's fishman empire in the East Blue would have short-lived the moment the Marines caught wind of it.
Crocodile's military state would have been short-lived if the admirals were ever deployed to Alabasta.
It's much simpler than you think. Big Mom protects Fish Man Island in exchange for candy. Hody's men eat her candy, meaning Fish Man Island can't up hold it's end of the deal. Hody takes over Fish Man Island, but can't pay Big Mom. Hody is now an enemy of Big Mom. Hody was screwed on soooooooo many levels and he didn't even know it.
