Why would a Saint Seiya become a pirate?

Follow the ship! The main character has fewer scenes, it's not a babysitting story! Taking a bath in Akainu's lava. Skating in Aokiji's frozen ground. Reading under Kizaru's light. Training in Fujitora's gravity. And when there's nothing else to do, getting a massage from Garp's iron fist. Get Hawkeye to trim his nails with his black sword. While he's at it, have Kaido act as a punching bag. Have Green Bull feed the birds. The Flame-Flame Fruit is best suited for grilling. If you ask who the best talker in the world is, watch as my Saint Seiya warriors intimidate the villains. Yes, these Saint Seiya warriors were all trained by me. I am Fanny, the Saint Seiya instructor who has come here to sail.
