Protecting people? Vergil? Where'd you get that from?
I just told you. I'm going to quote him again so it sinks in.
"Might controls everything. And without strength you can not PROTECT anything. Let alone yourself". This is BOTH his mother AND whoever nero's mother was/is. Naturally this includes himself as well but that's obvious. He had a girl in his life Who he lost (AND his mother). That experience will make someone afraid of losing anyone that matters to you. You want to protect yourself, yes, but you also want to make sure you protect what MATTERS to you. You want to make sure you're STRONG enough to do that. Thus Virgil's quest for power. The thing is Virgil doesn't HAVE anything to protect other then Nero's mother (in the past) and now currently Nero himself. So naturally he only had himself and Urizen happened because only selfish. At no point do we see anyone that matters to him in any of the games except for the ending in 5 (and a bit of the reboot which shows the mother dying too). Except maybe Dante but I don't think we can count him. That said they do watch each others backs at times. You haven't SEEN Virgil's "love interest" and want to turn a blind eye to it.
Considering he had a girl in his life, who is likely dead (or at least lost) it only makes logical sense that his desire for power comes form wanting to protect what matters to him. He only says "That was a long time ago" but he does seem fond of the memory when he says it.
This isn't to be confused with "Protecting the common person" though. Virgil doesn't care about protecting 9/10 people. He ONLY cares about people that have gained his acceptance/loyalty. Which is very few in number. Practically none existent for the most part. He had ONLY himself for most of the time. Therefor Virgil gets used to being on his own and having no one to protect. Only caring about himself right up until the very end of 5 (Nero's son). But BEFORE 3 he did have someone. We don't see it in the games but it's HEAVILY IMPLIED. Actually it's been confirmed.
It's ALSO been CONFIRMED by Capcom themselves that had Nero lost Kyrie then he would have ended up like Virgil. So no, this is not headcannon. This is capcom cannon. I'll have to look through posts to find who said the name of who confirmed this (began with a H I think?). Nero cares for Kyrie. Which logically means Virgil cared about whoever nero's mother was (or is if she's still alive somehow and shows up in a later game). If that isn't waving a flag at "Lost loved ones that could have been protected better" then what is? That CLEARLY states "Wanting to protect anyone that matters" (IF they happen to be around. Which for Virgil was not the case for 95% of the series).
And he's "lighter" for a
reason. It's
because of Nero. Who fought for his acceptance. And thus Vergil now cares about him. Technically Nero was fighting so they wouldn't kill each other at first but the acceptance thing happens in the fight itself. Virgil actually STANDS DOWN when he can still fight. Which he's NEVER done before. He knows he has a son now. Not that Nero needs protecting much. Why do you think Virgil suddenly wanted to cut down the tree? If it's not Nero then it's the town. For he says himself "The roots will continue to spread through town". Interfering in his business is just an excuse. Virgil is too proud to say he cares about you.
Whatever way you look at it he's protecting something. And it's more then himself. I doubt he actually cares about the town himself. But Nero does. And Kyrie is in it. So there's that. I doubt he'd want his son to go what he went through. If Virgil only cares about himself then why TRAP HIMSELF IN HELL? That's a bloody sacrifice.
It's one cutscene basically. Virgil simply wears a white mask and calls himself V. That's basically it. It was probably an easter egg to the film "V for Vendetta".
