I think the story would have more of an impact if Sanctus acted like some sort of father-figure to Nero from the beginning.
So when Dante "kills" Sanctus, Nero had much more of a motivation to hunt and kill Dante.
This also becomes more of a shock when Sanctus turns out to be the bad guy all along, prompting Nero to rethink about f***ing everything.
According to the script, Nero assumes that the first Bianco Angelo he encounters is a "friendly" simply from seeing the Order symbol on it.
Since it's also the players first time seeing one, it's not much of a surprise to reveal that they turn out to be just another enemy.
I feel like the opening cutscenes of DMC4 should have shown the Angelo armors piloted by real Order members.
This is so that when it was revealed that the ones fighting Nero are empty, it would come as more of a shock to players.
