What i keep thinking is since Kaidou seems like a brutal pirate who would kill anyone getting in his way i would think that he killed someone who X-Drake cared alot for(family/,friend,or marine) and is probably just trying to get revenge. Since the World Government/Marines didnt care about his loss i guess he decided to go into Piracy in order to have the freedom he wants in order to get to Kaidou. Thats my guess.
