I'm not sure Vergil can actually be blamed for Urizen taking advantage of the tree.
For one thing, it's implied the tree's growth is a natural occurrence that happens on a set timeframe. And while Nero suggests Yamato is at fault for things (IE that Urizen opened the portal himself), could be that Sparda's seal was just so degraded after millennia that it could no longer stop the Qliphoth from breaking through. Given demons already had a history of being able to attack Red Grave, it seems likely it was particularly weak there. I'd even go as far as to say that the reason Sparda settled in the area around that time was because the Qliphoth was due to appear in the near-future.
Moreover, it seems obvious that Urizen's actions were never Vergil's plans. He intended to separate the weakness and corruption from himself just to fight Dante, but when Urizen was born he didn't actually care much at all about Dante. Instead he tried to invade and rule over both worlds, something that was explicitly not Vergil's prerogative. It seems as though Vergil had no idea that Urizen would deviate so much from his own desires, and that V trying to stop him is highly indicative of that.
Yes, that is the thing. Vergil and Urizen are
not the same person, so blaming Vergil for Urizen's actions makes no sense.
I disagree that Vergil holds no blame. First of all, it was because of his selfish desires that he created Urizen. Even if he didn't know what Urizen was going to do, he is at least partially culpable due to people dying at the hands of Urizen.
Secondly, I take umbrage with treating Vergil and Urizen separately as individuals. If we're accepting V as Vergil's inner goodness, then I don't see Urizen as anything but Vergil's inner darkness and that on some level, whether consciously or not he did want it and now without any inhibitors to hold him back Urizen could embrace Vergil's evil desires.
Yes, V is Vergil's inner goodness, and U is Vergil's inner darkness,
but neither of them is Vergil. Vergil deserves neither praise for V's actions nor blame for Urizen's, beyond the act of separating them in the first place. And on that count, he was quite desparate, and probably not thinking clearly.
@Veloran - What?
No my dude it definitely makes them him. V is Vergil’s good and Urizen is Vergil’s dark. If you’re saying they’re not him then how or why would V merging with Urizen “restore” Vergil?
Dante had Urizen beat and in realising that he (Vergil) was going to die, V merged himself with Urizen. Following this Nero asks what the hell happened to V and Dante replies “He returned”.
V, Urizen, Vergil. They are all and the same. So yes, they are him.
They are
him, but
neither one of them is
him. If you separated good and evil sides of
any human, you would end up with the essentially same outcome: a goody-good and a murderous psychopath, because good side would not be there to balance bad and vice-versa. The only difference from V and Urizen would be the scale.
Person is a balance of their good and bad sides, if they are separated that person is
dead.
