I think that Diavolo was the original personality and then he developed Doppio so  that he can continue his crime and act like a non-suspicious person while doing so, and the reason why I think this is why is because Doppio is very kind so if Doppio developed Diavolo, then 1. Why would Doppio be taking actions for his younger personality (because who knows if Diavolo can wipe his memory) and  2. Then he wouldn't be the kind person that he was, he would just be a mean person. Also, I think that Diavolo was the original personality because according to the wiki's Doppio article, it says that Doppio is the younger personality, so if Doppio is younger then Diavolo, then either when Diavolo takes control, Doppio doesn't age, or Diavolo is the original personality. I rest my case.
