how he likes to bounce off walls and party like a college fraternity kid...
Quick question, why do you think he does that?
but the writers can't dedicate one line of dialogue to explain why Vergil wants to destroy the world and everyone in it?
Wait, what? Where did you get that from? Vergil never wanted to destroy the world. In DMC3 his very first scene establishes that he doesn't care one bit about Arkham's plans.
The sheer amount of laziness on the part of the writers is astounding, but even moreso are the outlandish assumptions fans will make to substitute for actual facts. Could you imagine if characters were written in such a vague fashion in other mediums of fiction?
Last time I checked, writers usually get
praised for that kind of thing. Characters that are mysterious and with vague histories and motivations are some of the most beloved in the history of cinema and literature. Some that jump to mind are Roy Batty and Rick Deckard of Blade Runner, Patrick Bateman of American Psycho (Most people aren't even sure if anything in that book or movie even happened), and hell do I even need to say that the looming Darth Vader was a way more interesting character before his past as Anakin Skywalker was actually revealed?
Not to mention, that's a particularly valid way to characterize video game characters. The Dark Souls fandom practically exists precisely
because almost every character in those games is an enigma with no easily-discernable goals. People extrapolate tons of things about Kirk just because his body is found in a specific place, or determine that the Goddess Fina is in fact extremely manipulative and obsessive based purely on the wording of Lautrec's armor. Compared to stuff like that, determining some of Vergil's character traits from small clues may as well be like reading an open book.
Would we give two sh!ts about Marvel's Loki if his reason for turning against the Asgardians was 'left to interpretation'?
What. Are you sure you picked the right character, here? People argue about Loki's real motivations and the reasoning of his decisions all the damn time. Almost every interesting facet of his character, half the reason he's so popular, is that nobody is entirely sure what he really wants or why.
Would Castlevania's Gabriel's descent into vampirism have even an ounce of narrative weight if his reason for turning evil was 'left to interpretation'?
That's a terrible example. Gabriel's choice to become a vampire, and his actions thereafter, make no sense. His whole characterization after the main game is of someone totally given into despair, who doesn't care about anything in the world. So why become a vampire to save the world from The Forgotten One in Reverie? Moreover, why become an evil overlord
himself afterwards? To be honest, from those DLC I got the impression that the writers were simply rushing to try and explain away how Gabriel could become Dracula, and they ended up failing pretty badly.
Crucial personality flaws or hell-bent motivations for characters as important as the main villain CANNOT be left to the imagination:
A. They absolutely can be. Some of the best villains ever are characters that aren't so easily defined.
B. Vergil isn't the main villain. Not once in Devil May Cry has he been the only villain of any game he's appeared in. In DMC1 he's just a lackey of Mundus, and in DMC3 he's played by Arkham.
Again...a hollow excuse for a random assumption for something that is never once uttered, implied, mentioned or confirmed in-game or otherwise.
It's a valid viewpoint. At the very,
very least the fact that Vergil makes a distinction between what is and isn't a "true warrior" shows he has some sort of standards by which to judge.
So, the sharpness of Yamato depends solely on Vergil's "willingness" to kill things?
That's the theory we're going with here? But then, what choice do we have? It's not like the vague-as-all-hell GAME is going to tell us anything. Besides, wouldn't that mean that Rebellion can technically cut through dimensions, too...? After all, Dante uses it to block Vergil's blows all the time...
And I can't even count how many things have blocked Rebellion's edge...and plenty of them weren't on the size or scale of entire dimensions....
Rebellion is a Demonic blade that represents Dante's very own power. Kalina Ann is a Human-made rocket launcher.
Is t really so hard to see why Yamato could easily cut through one if forced, and not the other? Vergil doesn't even bother to push when he made contact.
I'm not really sure why you're so dead-set on wanting every little detail shoved in the player's face. It's not necessary for every bit of Vergil's character to exposited in order to glean details about him.
