Yes, because Laboon bashing his head against the rock wall for forty years has made such a difference so far.
As for Fisher Tiger… Oda told that part of the story VERY oddly for him, completely out of sequence and with flashbacks and flashforwards within flashbacks, one panel asides, jumping all over the place, fast recapping 20 years of history in one chapter, then highlighting a little bit more of that in the next chapter, then going backwards again, with Tiger arriving in town without fanfare and then with fanfare, and not showing the actual event in any detail at all, and then all mixed in with legend and heresay. (And bad translations did not help... but even those fluent in japanese and proper translations didn't help much.)
Was a slave, but not at marijoa. Escaped. Went to Neptune (in secret) to get an army and was denied. Went to Marijoa and climbed the red line and freed slaves. Came back to FI publically. He didn't talk baout what he had done. And then word followed, he got a bounty, and then the hgih class fishmen (Arlong, Jinbe, Hachi, etc.) quit their normal lives to join him as pirates, and the fishmen pirates were born.
Its either by far the sloppiest bit of writing Oda's ever done, or he did it intentionally to confuse the issue just a bit. (either way its sloppytho) You can debate if he actually climbed the red line or if thats just a myth that grew from no one knowing he was a slave, but...
-Fisher Tiger was a slave
-he did free the slaves
-he talked to Neptune about going to do it at some point
That he planned to do it and asked Neptune for help means he did not happen to be captured and then free others, there were actually two different jailbreaks, one for him alone, then a bigger one where he freed everyone, and that's where the confusion sets in.
There's no doubt about those three things, but the timing, exact order, and full extent of what he actually did are all blurry... and that's just down to the awful way Oda presented that entire set of chapters.
