There are seven virtues that historically run counter to the Seven Deadly Sins. The traditional list includes: Chastity, Temperance, Charity, Diligence, Patience, Kindness, and Humility.

The musical Camelot includes a song about the Seven Deadly Virtues. That modified list includes: Courage, Purity, Humility, Honesty, Diligence, Charity, and Fidelity.

As a follow-up to another thread, here's an attempt to associate the Crusaders with these virtues, based on a combination of their background and origins from the Citadel adventure.

SEVEN VIRTUES
Chastity = Evergreen
Temperance = Enforcer
Charity = Blizzard
Diligence = Manta-Man
Patience = Dreamweaver
Kindness = Laserfire
Humility = TEACHER

SEVEN DEADLY VIRTUES
Courage = Enforcer
Purity =  Dreamweaver
Humility = TEACHER
Honesty = Laserfire
Diligence = Manta-Man
Charity = Blizzard
Fidelity = Evergreen

I don't think these are as much fun as the Seven Deadly Sins ...

It's easier to associate heroic and good-sided characters with the Seven Deadly Sins than the other way around.

Here's an attempt to associate the Destroyers with the virtues. Some of the associations are ironic out of necessity.

SEVEN VIRTUES
Chastity = Ratman
Temperance = Behemoth
Charity = Shapeshifter
Diligence = Dr. Apocalypse
Patience = Annihilator
Kindness = Electrocutioner
Humility = Iron Maiden

SEVEN DEADLY VIRTUES
Courage = Annihilator
Purity =  Behemoth
Humility = Iron Maiden
Honesty = Electrocutioner
Diligence = Dr. Apocalypse
Charity = Shapeshifter
Fidelity = Ratman

I think Fortitude should make the list.

I realize this is a classical list but I never considered Chastity a virtue. The girls I dated back in high school posited a dissenting opinion but never me.
