I'd hate killing Julius/new Belmont, also Alucard
Can we especulate on story?
I think Dracul makes Trevor Alucard as a punishing him to feel the same he did (Killing Sypha and stuff, because she dies, and that's too bad) but he ends up being good. He Kills Simon, too, because fuck him, but Simon could seal him by some years (100?). Then he awakens without control over his castle and the events of the trailer happen. Then he kills Alucard and goes to exile. Then in 2012 a new Belmont rises against him, but he kills him anyway, but the feels remorse so becomes good because of Satan.
As sad as that sounded, at this point of melodrama feels very plausible :not a fan of the new kill-everyone-to-feel-emotional- direction of the story:
