One is a villian unhuman and his clan kill a little dude and he cuts off the arm and eats on it while looking off in the distance..another scene is he is trying rape a human woman and he says “finally before I kill you ” and drooling on her she hits him and knocks him off.third thing I remember is another unhuman is helping a woman he build a fire with a cigarette lighter tells her humans is how he got the lighter.its been 25+ years I maybe foggy on the memories any help would be grateful
