I don't think evil is really the right word to describe Vergil. Insane seems more accurate. He shows no signs of even being aware that his actions could have caused the extinction of the human race, he didn't seem to have any idea what he would do with Sparda's power and he seemed genuinely unable to understand why Dante would be uncomfortable with the idea of opening a hellgate in the middle of a city in order to retrieve Force Edge . His desperate need for his father's power seemed to be the only thing he was capable of thinking about.
Vergil's actions were not good, they can't be justified and it is very unlikely that he was planning on doing something good with that power or even had any plan for what to do with it at all but you can't call him evil because he wasn't completely sane. Evil people intentionally harm others for their own benefit and completely understand that their actions are wrong. Vergil clearly does not.
on topic: (remember this is a thread about DmC Vergil's appearance not DMC Vergil's morality)
his clothing should be mostly black with a bit of blue (to match Dante's black and red coat) he should be wearing something that seems more sophisticated and formal to contrast Dante's punk look. (a three piece suit would fit the theme best but i am not sure if it would be the best look for him.) he should have black hair in the same basic style as DMC3 Vergil but shorter to be more realistic (excessive use of hair gel isn't really a sophisticated trait). obviously he needs to have Yamato and it has to still be a katana. it's hilt and sheath should have a similar design to Rebellion's hilt (Sparda's swords should match.) since DmC is supposed to be more modern and realistic DmC Vergil should use a gun.(i think a demonic looking revolver would suit him). he also needs demon and angel weapons . (DmC versions of Force Edge (demon weapon) and Beowulf (angel weapon) would work or maybe make Yamato the demon weapon and Force Edge the human one.)
