Lawful Evil is great and all but I'm curious on examples like Dredd or motivations for a Good Conquest pally.
Hatred of Undead is easy, ruling Barovia properly instead of keeping it a snowglobe is a possibility.

The only thing that is an issue with Evil atm is there are some things in this campaign that could apparently do something nasty to me if I am already evil. But there are apparently relics that can force an alignment shift
