So it turns out in DMC5 Vergil was the cause of all the trouble due to splitting himself into Urizen and V with Yamato. As Urizen he killed an entire city basically and spent the game thrashing around Dante, Nero, Trish, and Lady. Once he returns as Vergil he immediately tries to fight Dante and doesn't seem to even care or acknowledge the chaos he did as Urizen. Yet despite all this at the end of the game Dante seems willing to patch things up with Vergil, while Nero doesn't acknowledge him as a father, he stills acknowledges him as family. He basically gets off with a slap on the wrist. By the end of the game he and Dante have reformed their brotherly bond.
