For two consecutive chapters, Vegapunk mentions how WG vs Joyboy clash was merely ideological, not between good vs evil. Roger-Rayleigh knew the history and still takes the battle vs WG as fun and games. You know where this is heading right? There is a good chance Oda will prove in the end the WG is not inherently evil. The only person who made the pirates and marines to team up and defend the scumbags of WG was Xebec, i.e. Roger thought Xebec was way worse than the WG. History will repeat, but this time Xebec's replacement is based on Oda's favorite real life pirate - in fact the most famous rl pirate of all time - who will have gura gura, yami yami and at least one ancient weapon.
