And Crocodile tried to destroy Alabasta and overthrow a kingdom, starting a civil war that killed lots of people in search of a poneglyph.
For the most part, he kept things stable with no need for slaves and despite instigating a civil war the country was doing rather well financially.
That's why he hid in paradise after getting a beat down from Whitebeard.
And then went on to try to attack Whitebeard the first chance he got, and went back out into the New World.
Who was a woman till Ivonokov stepped in.
Except for all of them.
He directly assaulted Akainu without hesitation, the strongest of the three admirals and walked away unharmed. He'd have attacked Sengoku if Doflamingo wasn't distracting him.
He was a warlord Nothing stopped him from visiting Marijoa and doing just that.
Pretty sure Shichibukai are only able to visit Marijoa during summons.
Pretty sure after Hachi's experience that would not be the case.
Jinbei is a man of compromise who is shown never directly challenging someone unless he has support.
