well yeah. its an option. whether you want to side with the seekers or with richard.(quest is theres a famine in rivertown) see what items richard drop. then you are to be blamed after killing richard in the flames of vengence when i think you rescue anne from general luxurious. haha
but i think you already know, isnt it??
In fact I killed Richard (I got an instant dislike of the character and it was a pleasure to slit his throat) and never heard a word about it in FOV. Even when speaking with Anne (I convinced her to broke up with her lover, I'm that gentle).
