@moud:
lol there's nothing set in stone in one piece evil and good exists in all groups even the celestial dragons had people like doflamingo's parents and their descendant is evilness in its finest form your statement "descendant of some evil part of the D.clan" doesn't go with the one piece theme
What do you mean, exactly? How does Blackbeard being an evil descendant of the D Clan" not go in line with the One Piece theme? Every member of the D. Clan smiles and takes death as if it was a happy occurrence; Blackbeard did nothing of that sort. Even Saul, a giant, smiled when he died. This means that the 'smiling at death' aspect of the Ds is intrinsic to the clan as whole. Now, Blackbeard, who is D himself, does not possess the trait. He is, more likely than not, as I already stated, a descendant of Ds who betrayed the D clan or something. Why can't you see that Blackbeard is crucial to the Void Century plot line. Its pretty apparent at this point, but you continue to refuse it.
they'll have their fight D or not luffy will have enough reasons to fight BB , finding raftel could have something to do with being a D that's why WB said to BB you're not the one roger is waiting for you guys don't have a single reason for why luffy'd have to fight another D for history purposes ignoring the fact that Ds are the celestial dragons' natural enemies
Have you ever considered the possibility of both Luffy and Blackbeard inheriting Roger's will, both finding One Piece, and doing there own thing based on the treasures contents? That is what is likely to occur. Yes, I could see a minor clash between the two forces to occur at Raftel, but their final showdown occurring before the great war is preposterous. And, as Monkey King and I have already stated, the fact that there is 'evil' D among a bunch of good doers has to amount to something.
