Well, you start by downloading season 2 and installing it, it's treated as a separate game so don't just overwrite S1 folder, if that is not working for you should explain exactly why you can't.
The things she did with Claire in France was evil though besides Noel i dont think any dark one Cares enough about human life to be good or evil they only seem to care about the human they are bound too and there spot in the hierarchy. So maybe you are right feels weird for her to be bound to a male though, I expect her earlier to bind to Claire then a male personally
I am just going by her explanation. She said that she would have brought humanity back under dark one control without spilling a drop of blood. That to me sounds like she wanted it to be relatively nonviolent. Now she probably didn’t want non-violence because she cares about humans, probably just to impress Nael. I’m not sure we could ask for more from a dark one who has never had a bond to another human though. That is far more consideration for human life than I would expect her to have given the circumstances.
