I wanted to bump this thread, because it's something I haven't really seen discussed.
The first part in particular is a bit immersion breaking - if you fight to protect the Inn as Dark Urge, but fail, all you get are dialogue options expressing how joyful you are at Last Light being destroyed. When you inevitably have to kill enthralled Isobel at the end the Act, even though you don't necessarily lay a finger on her, the game treats it as if you deliberately killed her (thus granting the slayer form). I don't necessarily mind this, in the sense that (willingly or not) you killed the desired target, but it's a little frustrating to have dialogue largely act as if you deliberately chose this.
