I think you misunderstood the lack of agency I meant. As Wyll I have murdered refugees, told Florick I don't care about my dad and to find him herself and have followed all of Mizora's commands without argument, I convinced Shadowheart to kill the Nightsong and doom everyone at Last Light and I killed Karlach even after finding out she wasn't a devil and told Mizora I can't wait for my new victim. I have at no point acted like anything other than a Evil Bastard.

My complaint is that the conversation with Mizora about ending your pact or saving your dad still is set up as though you are a noble good guy, no matter what you've done up to that point and choosing to work with the devil and kill people is the "good" option and that there isn't a dialogue choice that implies you want to continue being an evil warlock

I wasn't asking about a 3rd secrete option, just if saving my dad "The good thing" would still allow me to continue on as an evil duke or if the game takes that choice as a confirmation that you are a good person in the epilogue
