If the awnser isnt obvius, I will make a discussion on the reddit to choose the best option.

YES: They are like Cobra, they are like Luffy,

NO: The 20 kingdoms fighted the ancient kingdom because the ancient Kingdom were assholes. The Ancient Kingdom is like Wapol, Imu doflafingo and that type of shit

Oda wont awnser☠️: Oda forgor or didnt mentioned this part.

Split: Some parts of the Ancient Kingdom was good and some parts evil.

Gray: Not Good, but Not Evil. Least likely option considering that Oda is very black and white with this topics.

I fused the Gray and split because it is very similar

Other: If any of the opitions are right, I will choose this one.
