It's worth noting that many who run multiple games have one version of Good for D&D/Pathfinder, and a wholly different one for other games...
Partly because some games define evil quire differently. Or, such as palladium, several different kinds of evil differently. Many others lack a clear game definition but have setting definitions. Or a few have no definition of evil.
And partly because some use their own personal definitions even when running D&D, but use the book or the GM's call when playing in someone else's game.
I'm fond of Pendragon's approach...
Evil is typified by the following 5 Traits: Vengeful, Selfish, Deceitful, Cruel, Suspicious.
If they're all 16+, you're playing a thoroughly evil bad person... and not for long, because if they stay that way over winter, the character gains the evil religious bonus, but you also lose control over the character, who is now an NPC. (At least in KAP 4.) If they're all 11+, you're still evil, but not evil enough to be NPC-only... It is, however, just barely doable to be a chivalrous knight and evil... but you must then be superhumanly Energetic, Just, Modest, and Temperate... if they are all 19-20, and you don't max out selfish and cruel. (And, yes, such a knight would be super hardcore Lawful Evil in D&D terms...) Had that happen once... player started with the evil bonus and I gave them one adventure to drive them down... he failed. That was due to random rolls.
