A paladin is per difinition a holy warrior, and since the term "holy" is per difinition "good", then per difinition a paladin is a holy, good warrior of good church!!!
If you want an evil version of a paladin well then Black Guard or Fallen Paladin is the choise for you.
But having a neutral or evil paladin is per difinition NOT possible!!!
For the record, 'holy' translates directly as 'separated' and means roughly 'that which is set apart from worldly things'. In a fantasy world such as the Realms where all the spectra of alignment have representative deities, one *could* be 'holy for Bane'. Not trying to be snippy, but as Wooly said, it isgood to be precise in use of language.
How can life be so bountiful, providing such sublime rewards for mediocrity? -Umberto Ecco
