I think as far as edginess will go, perhaps the debate on whether Vaccine or Virus truly determines whether or not you'll turn out good or evil could come into effect at some point.

While I think of Adventure 01, most the evil Digimon (that were not controlled by gears) were picked (or maybe placed) in the virus category but I feel that there is merit to the way Wikimon put it in their Attribute article:
[quote=Wikimon]In a more general sense, they can also represent personality types:[List]
[*]Vaccine: As a rule, Vaccine digimon are usually good, put a high emphasis on justice and morals, and fight against evil.
[*]Data: Data digimon can be good or evil, but generally value peace above all.
[*]Virus: Virus digimon desire power, and can often become greedy, selfish, wild, or evil in pursuit of it.
...All of the above is not set in stone and there have been heroic Virus Digimon, as well as villainous Vaccine digimon.[/list][/quote]

I actually like the idea of using purple Elecmon for the Child/Rookie though it makes the line shaky with Virus Child, Data Adult, Virus Perfect and Data Ultimate (it actually makes the line appear to have some consistency though.)
