One Piece: Might Makes Right

During the Paramount War, Garcia, a Devil Fruit User known as the Mad Thunder, executed the “noble” Celestial Dragons. With words that blasphemed the gods, he ushered in a new era. Justice? What is justice? You hunt pirates because they persecute you, and call that justice. Why isn't it justice when we hunt the Marines who persecute us? On these seas, the Marines slaughter civilians and traffic in people, while pirates protect the people and rescue slaves. So what is justice? It's power. The World Government was stronger than Luo Roger, so the Pirate King's bloodline was deemed more evil than the Celestial Dragons. Now we're stronger, so we're the righteous ones! Members of the Dawn Pirates, in the name of pirate justice, slaughter the Marines and leave none alive!
