I'm think the MC should have a humanity stat. Without a morality meter, I have some worries that the MC will be railroaded into being a stand up vampire bloke. The story so far does seem like it will give us some choices regarding this matter, but who knows?
What I really liked was the fact that the "evil" choices so far all had some justification to ease us into the darker path. Well... except how we treat Laurie. Why can the MC be so mean to her?
Treating the hunter girl as food is totally justified in my books. She would have killed him without hesitation, doesn't matter what her backstory was. Using Whispers is justified. Exploring new powers is only natural and MC is getting blue balled harder then a Tibetan monk by Sharon. Making him regret it afterwards is a nice touch. MC isn't quite ready to go full darkside yet.
