    Indeed, a thief is a thief, why all the nonsense? You go to sea flying a pirate flag, who else but you will die? So what if you call yourself a visionary? Flying a pirate flag is an open secret, and you still have the nerve to argue? Saying the Navy is bad, yes, there are bad people in the Navy. But so what? Every year, just as many Navy personnel die trying to kill pirates as you do, right? Are the Celestial Dragons the scum? That's certainly true. I don't need to elaborate on how your "good" pirates get their money for entertainment, do I? By robbing pirates? Today you think robbing pirates is a quick way to make money, tomorrow you'll dare to rob the government to get rid of trouble. All that boils down to one word: thief. If you're not a thief, if you don't fly a pirate flag, you wouldn't be in this mess as a bounty hunter. But you insist on flying a pirate flag and claiming to be a good person. For example (a good pirate kills a group of bad pirates in a city, and this news will reach the ears of everyone in the city. Subconsciously, everyone will think you are heroes, think you are good people, and think being a pirate is not bad. If there were a Marine in this city, what would you think if they saw a child wanting to become a pirate?) I really don't know what you authors are thinking? And you even introduce the idea that there are good pirates. This is pure pointless nonsense.
