Being a pirate seems fun and all but the reality is, you have to either be extremely lucky, or extremely strong😬. It’s the Marines for me. Stable growth in strength and whatnot😌

I would pick a pirate and tried to make a crew of each individual race.

I picked pirate because come on, being a civilian would be boring in that verse. Also if there is a chance where I can use all Haki then definitely becoming a pirate but regardless I would go to travel in the Grand Line

Marine.

Bro, let’s say you rank up through the Marine system, would you really protect a Celestial Dragon ? Or be like Garp ?

And would you really like to be a serial killer searched in the whole world?

People in OP fandom use to have the so wrong idea that the Marine is evil and the pirates are all like Whitebeard or the Straw Hat crew. Hell no, OP world is a place of suffering and pain because of them, there have been slaughters, violations, injustices....

Of course I know the Marine and WG are not angels, but at least they help people somehow, the admirals are the reason why a bunch of people hesitate about becoming pirates and some pirates quit being one. The Marine was not the antagonist at Marineford, Magellan's crew was not the villain at Impel Down, they were just ensuring those pirates/prisoners could never hurt anyone.

That was actually a serious question though... anyways I will respond with this Kid quote:

“World Nobles... Slaves... Human shops... Against the "purity" of these "upper classes", the villains of the world look positively humane in comparison. It's because the world's in the hands of scum like them that it's all screwed to hell... I mean, we're not the nicest of guys, but at least we're honest about it.”

Anyways, I wouldn’t turn into a serial killer though. I would just travel the grand line as a pirate & definitely hunt for some treasure! $$$$

Edit: The WG can chase me all they want but they’ll have to kill me.....

Honestly, I'd be a civilian but I'd specifically be an adventurer/explorer, just traveling and sketching new discoveries and experiences. Of course though, I'd be travelling with the safety of my devil fruit :D

Remember Pedro? The explorer guy?

Get ready to be labeled as a pirate.

Two of my main choices weere PIRATE and MARINE, but I weighed them and realized that I'd rather be a Marine since pirates have so many enemies (maost of them are their fellow pirates)
