I am in the middle of my second play through, and decided to go all the way chaotic evil.
To me it is difficult to play a real chaotic evil play trough because :
1°) your companions keep disapproving what you do, but still follow you and don't really confront you. It just feel bad and forced to me.
2°) i am concerned about the impact on side quest and XP that this route procure.
Maybe a fix would be able to recruit new companion that are more... chaotic evil ? there is a certain charm, in doing evil things, and not being able to fully trust your powerful ally . I mean, if you want to allow player to be the bad guy, go all the way please.
