The problem with Alessa was that her innocent side had been torn away from her, and trapped inside of some device. There was nothing innocent inside of this vessel. There was no voice in the back of her mind telling her to stop. Pure and simple, what was left inside of Alessa was nothing more than a monster, a demon.
Calmly she walked up to Sam, and looked him over for a good while. Once she was done she shook her head, and said, "If you think there's a tiny little voice in my mind telling me to stop, you're dead wrong."
While she had been saying that, a white glow formed around her right hand. It wasn't as intense as it could be, but what she was going to do next would probably hurt. Her calm demeanor quickly turned into one of pure rage as she lifted up her right hand, and brought it hard across Sam's face.
