While the Akatsuki are an evil organization, not all who join have evil intentions- do they? Consider Itachi Uchiha, is he really a villain or more an anti-hero? Maybe an anti-villain? In any case, while we don't always know his motives, we know he looks stylish in his Akatsuki ring customized with the kanji for Shu, Japanese for Crimson, Scarlet, or any of the cooler words for shades of red. Itachi wears his on his right ring finger, but you can wear yours as you see fit!
