It's like when you play as Dark Urge. During the scenes and the dialogues to your character is given the opportunity to react differently based on how you imagine your TAV is: you can make him smile and get excited at the idea of killing or torturing; have a neutral reaction because you are curious; or reject the dark impulses completely out of disgust. Playing as Dark Urge I find it more disturbing than AAstarion, yet there you are given the opportunity to react as you like and there is nothing that forces you to be a good Dark Urge... perhaps just the indignant comments of your companions. So, again, I don't understand why with AAstarion the TAV can't have the same broad possibility of responses and reactions, but you have to play only like a victim.
Durge is also made to feel bad about Alfira in the epilogue. They could have instead narrated the story about you remembering her and then having options to select how you feel about it, but instead the narrator decides you're remorseful. How about a scenario where you saw yourself as a victim of the urges and didn't care for others and you only wanted to be rid of Bhaal's influence so you could be in control of yourself and dominate and murder enemies together with AA, which you can even choose in the dialogue options with him? Another contradiction.
