Stewardship. That is the reason I can not simply give in to every urge I have and pillage everything around me. It is what keeps me from climbing those stairs and causing mayhem and destruction, much as the idea appeals to me. I must be honest though, it is more than just self control and restraint. The sickness that tends to run rampant in the sort of people I am speaking of turns me stomach. Just as a human would shy away from rancid meat or soured milk, I avoid feeding on the dregs of human society as much as possible. A pity, in all actuality. Were I to feed more on the lower life forms and forgotten souls, I might provide a better service to "the crop". I do, in quite a few situations, tend my herd and cull undesirables, but that is another matter. I perform that service for the good of all, for the welfare of my crop and largely because they simply piss me off.
Nothing tastes sweeter in my throat than the torrential gush of blood pouring from the ragged gash ripped into the neck of a pedophile or a rapist. I am not particularly fond of humans, but there are those among them that are not even worthy of being referred to as a person. They are subhuman. Even their blood is tainted, I don't drink it, but spit it back upon the ground after draining it from them. There is no sweetness in their blood. Rather it is the sweetness of righting a wrong, avenging the innocent and stopping the horror from happening again. That sweetness is intoxicating and I indulge in it, time to time.
For the most part, I am much like any other hunter. I seek the perfect prey. I seek the perfect setting. I am after not only fulfillment, but am also mindful of my immediate and long term welfare. When I feed, I must admit I prefer to dine on the fine and delicate bouquet of a woman. Men will do and I suppose I take that route most of the time, but for a truly "tasty" treat, I hunt the streets in search of a woman. There is food and there is food, and then there are delicacies. Drinking the blood from some dockworker or truck driver will keep me alive and most times I am satisfied with them, but there are times...
Sometimes it is the joy of toying with my meal that pleases me more then the sustenance itself. Sometimes it is the rarity of it.
