Honestly anything can work, i dont believe any one class has more "evil" options other than maybe Oathbreaker Paladins

[Keranik]

L1 Rogue/L11 Ranger

Depends on the type of evil. And what kind of advantage you are looking for.

- If you are murder hoboing as a Dark Urge then Assassin or Gloomstalker play fantastically as they like to 1-shot enemies before starting conversations. Kill first, talk to corpses later.

- If you plan to "Work Alongside Evil" you may want a Charismatic approach for Intimidation checks. Paladin, Warlock, Sorcerer work nicely. Lloth Drow and Duergar also get lovely "evil" dialogue.

Half-Orc Barbarian Berzerker that multi-classes with 3 into Fighter Champion, take the Great Weapon Master feat & the fighter class passive Great Weapon Fighting.

You end up with being able to make raging, multiple, extremely hard hitting criticals that also are easier to roll.
