Fear. It is one of the major driving forces in the world. Fear causes baseless hatred. Fear can turn a U.S. Marine into a sniveling infant. Oddly enough, fear can also be a drug. There are those that crave pure terror for their own amusement. Whether they be experiencing it... or inducing it.
It is more than an adrenaline rush for some. It can be sexual. In Shaid's case, it can be nourishment.
Are you afraid of the dark? You will be.
