Or certain people seeing him as mysterious because they see only what they want to see. DMC3 Vergil's goal and motive were
painfully obvious. He started out with gaining power with good intentions, but then slipped to the dark side and only wanted power for himself. The protection thing was an "honor shield".
"I'm doing this but
only for the greater good." Yeah, right. It's as if he really expected DMC3 Dante to believe that. But Dante himself said that Vergil
wants to break the spell over the portal and turn everything into demonville. So, either Dante is wrong, or Vergil is lying to make himself look good. Or Vergil himself is just flat-out delusional. And I don't think Dante would be wrong about something like
the entire cause of the game's (paper-thin) story.
The reason Dante didn't argue with Vergil is because he
had an o-katana that went right through him at the time. It was like when Dante sliced Vergil (almost) in half, "Darth Maul-style". Vergil couldn't speak for a few seconds after that because, like Dante, he was too weak to do so.Vergil was pretty much a pez dispenser at that point.
BTW, how cool would it have been if Vergil split in two when falling down the waterfall? I mean, sure, he could inexplicably put himself back together, because
