I also would have liked the option to kill Quinn, but I understand why they didn't give it to me. What I don't understand is why I didn't have the option to slap a slave collar or something on him. Seems like that could have been handled pretty easily. Plus, the idea that you can be maxed out affection with Quinn and still have him betray you is garbage. They could have at least wrote something into the story where if your affection was high enough he warns you about the ambush and you play it out anyway, if they felt that encounter was important enough to be impossible to circumvent. They could have made it a whole master plan where quinn pretends to kill you and you use it as part of your defeat of Baras...instead....bah.
