A runaway princess doesn't do much. He doesn't know any intelligence about Masa aside from being a King. From his perspective Vivi isn't that much of a threat. And we all know it, without the Strawhat pirates help she can't do shit about Crocodile and his plans. So with or without Vivi, Crocodile can still continue to proceed his "Utopia" operation.

It is just to force the plot to get Robin into the harem

I don't get what Crocodile's intention of going after Masa. Like he doesn't have any motive to do this plot. He has his own problem in Alabasta. Poneglyph or the Ancient Weapon intelligence is in Alabasta. Don't know what his motive is on attacking another country that does not give him any benefits in his "Utopia" project

Then all the background supporters of Luffy will emerge 1 by 1 and avenge him. Then Masa will kill all of them in 1 chapter. Next chapter he will also go to Mareijoa and kill all World Government officials. One Piece story done.

Then you could also recruit and conquer a top swordsman as a worker. Mihawk is just a pure swordsman fanatic. If Masa could just fight him once a year with sword duel. I think Mihawk will probably agree after all, he could not defend and counter attack that 1 strike from him. What a waste of resources Akikan. Could have an Admiral powerhouse right off the bat.

People are resources, instead of just killing them directly. It will be better to conquer and use them. But well that's Akikan for you.

Wonder why Arlong didn't start his PTSD after seeing this devil fruit.
