The Dormant Gene

Is it possible? Could a beautiful fun loving girl suddenly become a psychopathic killer? Could she, at the blink of an eye, turn so ugly on the inside that murder becomes almost second nature to her. If so, then surely, she must have already had some inherent biological abnormality. Did she possess some rogue gene; some evil seed that just needed a little prodding to bring about such a change. How many of these illusive seeds are out there? Is there one in you or I? and if so what is the key to activate it? Just what level of traumatic suffering does it take to awaken the Dormant Gene?
