Raz he is right. DMC´s storyline went to hell after DMC 1.
Have in mind the Vergil you´ve seen after DMC 1 is probably not one that DMC story creators had in mind when they introduced Vergil.
Hideki Kamiya said this:
"Everytime Dante was introduced he was different than whom i planned".
And using DMC 3 manga as proof to say "Vergil is evil" is really stupid.
The memory of Dante remembering his and Vergils birthday does not tell me Vergil is evil.
It tells the memory of two brothers being happy.
This is why i dislike a game team to dissolve
Now i will never know the story of what happened to Vergil and if he was truly evil!! Dammit!
