there is a genuine complaint in there being a lack of 'evil' content, like if you side with the refugees in act 1 you get to see them subsequently throughout the game along with their side quests, whereas if you go the evil route and off them, there's no 'alternate content' like seeing more goblin characters or something to replace them. as early as act 2 the option of good/evil kind of breaks down when the main quest is so linear as to just be 'kill this particular guy, no he can't be reasoned with, sided with, talked down, or result in any kind of outcome that doesn't involve a boss fight and his death'. further, pretty much every side quest in the game revolves around 'person needs help, so you help them'. if you're playing evil, very often the only evil option is to not do the quest, arbitrarily kill the person, or do the quest and then be demanding about payment after the fact.

none of this to say that the game needs to be more racist of course
