What is even more going for this possiblity is the fact that , since the D. are the ones who are supposed to bring “the Dawn of the world”, one of the equivalent word for Devil is “Lucifer” and in Latin “Lucifer” literally means “the one who brings light”.
3 – Dream/Dreamer
In my opinion this one is the most likely to be the significiance of D. Roger said before he died that the One Piece is “what every man can dream of”, and we know that the will of D. and the One Piece are completely connected.
The story of the Straw Hats is a story of people going on a journey to achieve their dreams.
In general One Piece is a story where the strongest character is the one who have the strongest will to accomplish his goal. So I think that’s what it could be the Will of D., the will of Dream, the will of the people who will do anything to accomplish their dreams. And since most of these dreams are related to freedom in some way, overthrowing this tyrannic organisation that rules the world, it’s a necessity to see these dreams come true, which is why the ones who have the Will of Dreams are the natural Enemy of Gods, because they won’t accept the natural order of the world if it’s in the way of what they want.
