I do agree that evil, warped/mirrored/corrupted/whatever versions of paladin's shouldn't be called Anti-Paladins, though. That's fucking dumb, who calls their profession/"class" a name based entirely on its opposition to another? Same with Dark Knight, etc.
Anti-Paladins/Dark Paladins should have a unique name that evokes something beyond "think up that other guy, but with the colors inverted." However, evil paladins have so many different themes there's probably no universal name. Do dark paladins reject the compassion and honor of a paladin while retaining the charisma, becoming cold-hearted and calculating Warlords? Do they reject the idea of defending others and become a horrifying whirlwind of violence known as Ravagers? Or do they abandon salving and protective magic in favor of destructive controlling magic and keep the focus on heavy arms and armor, becoming some sort of Marshal of evil creatures?
>tl;dr it depends on the setting.
