/No, no, Zelda Queen, the only reason why Raoul is ebilz is because Meyer said he is ebilz./

Which is pretty much the only reason why James, Victoria, and the Volturi are evil, too. I think that Meyer said at some point that she wanted to show that everyone (including vampires) is everyone's child and so shouldn't be immediately judged and discounted as evil, but apparently that goal does not extend to her villains.
