Yes, and i kinda like that thought.
Something kinda misunderstood by people in this forums about Vergil comes around two things:
1) His relation and thoughts about humans, and his condition as half-human itself
2) The kind of honor he had
And that gives argument for something major about his personality: that mindset of a warrior, a demon warrior to be specific. He sees himself this way and he wants (even if he try too hard) to be this way, he want that power that his father had, and even if he shows respect to his father (because of how powerful he was), Sparda was the only demon that kinda had a human side and that was the whole point of him despising humans"weakness" as Vergil sees it (remember that Sparda became a common mortal guy after sealing his own powers); that's why he despise human emotions and traits in general, it's not that he hates human, he's uncomfortable with the idea of being part human and that making him a unsuitable warrior: he's kinda insecure about his own power and abilities: but why? The hint DMC3 left for us, is that he blames himself for not being able to protect something (most probably, his mother), that line after the first battle with Dante leaves this explicit. That's why he despises humans "weaknesses" (that Dante sees as a strenght), it's not that he truly hates human, he do not reached that point yet. Something common in the asian philosophy is that thing about opposites and became tainted by some dark side, look at Evil Ryu's description and make the contrast with normal Ryu:
"As Evil Ryu, he becomes quite demonic and rage-driven; while his anger is not mindless, he has cast aside his respectful ways. Like Akuma, he enjoys power, and seeks strong warriors to fight to the death with. He truly hates what he perceives as weakness from humanity, such as love, family, justice and vengeance."
Coincidental, huh? Not exactly, that is kinda the cultural background they have for their symbolic representations of evil and good.
Going back to that "warrior mindset", that's were his honor sits too. Vergil's honor is all about combat, fighting, even in his most tainted form he showed honor (in DMC1, as a gameplay feature itself, Nelo Angelo will not attack you until you face him directly, unless he was already charging some attack when you give him your back). That's the kind of honor he have, he wants to be a "true warrior", he wants to test his own skills in a meaningful way, he wants power and improve himself as warrior; that's why he "despise" firearms and consider them to be unworthy of a warrior, they do "all the work" by themselves; that shows one opposite between Dante and Vergil too: Dante sees fighting as a way to have fun, in a lighthearted way (remember the ending of DMC3), Vergil sees fighting fundamentally as way to improve himself and to become more powerful.
I remember some post that someone made here in this forums, with some commentary extra-game by devs telling the idea behind Dante and Vergil is that they were suppose to be kinda a counterpart of each other, an opposite pole, shadows; and that was symbolized by their colors of choice (Red, the color of Eva and a vibrant, vivid color) and Blue (more of a morbid color), and remember: Red + Blue = Purple, the color of Sparda; so they are essentialy trying to simulate and embracing opposite poles of their father's own existence. Going on into this, remember some things about DMC3 story: he proposes to Dante to share their father's power, this is ultimately a sign of caring considering what he says after (and his "selfishness" about power in the whole game) : "Without power you cannot protect anything, let alone yourself". In the final battle, he again shows that he kinda struggles to sustain this "cold devil pose", when he is falling in that abyss, he gently swings Yamato into Dante's as a final token of his existence, what kinda implies that he accepts his human side (even in a very "unique" way, without saying anything); and Dante "confirms" this symbolism by keeping the gloves in his desk by the end of the game, side-to-side with his mother's portrait; it's cool to remember too that last Vergil line when he's going to take on Mundus: "It will be fun to fight with the Prince of Darkness. If my father did it, i should be able to do it too"; notice that subtle change of posture, he now shows that he wants to fight for the sake of fighting, he does not mention anything about power and does not even show his common arrogance, this could mean what was said before: he accepted his human side along with the weaknesses that comes with it, this in parallel with the Dante line in the end: "That's what i live for!" (talking about stylin' on demons), makes this argument stronger, as they show the same mindset in the end.
tl;dr Vergil was in self-denial the whole time, ultimately he had compassion for those he loved, he was able to love too and show signs of this to Dante; and Dante symbolic represents humans, the human side of Sparda that he choose to embrace.
