"There seems to be more to it than at first glance, doesn't there? Indeed, dark witches and wizards are not particularly bothered by causing harm to others, generally as a result of aiming for some greater goal. Some do harm others for pleasure but as a rule, there is a motivation behind it. Those of you who mentioned Power as a motivator are correct, fear is another motivator. Why do you suppose fear is a motivator for a witch or a wizard to master the dark arts?"
