Well, I think he was sorta taunting him, plus not liking someone doesn't mean you hate them. I know alot of people who dislike their siblings, but they don't hate em. ^^
To respond to Verilissexy, actually Dante did tell Vergil he was fighting him "just because I don't like you" but that could just be taunting, so yeah, I see your point. I did get the feeling from DMC3 though that they really didn't like each other. Respected, maybe, like, no. But meh, who cares. Anyway, as for the mom, I actually think it would be Trish too, but I still find the prospect of Dante having a child with someone who looks just like his mom a bit ... unsettling.
