There Is No Blood-Starved Deity:
Emotion As Magical Power:
Strong emotions generate energy within magical ritual. LaVey highlights three particularly strong emotional sources of power: the death throes of a living creature, anger, and orgasm.
Satanic magicians primarily draw power from themselves, and magicians can certainly do this through the channeling of anger or orgasm through sex or masturbation. With these tools at their disposal (and not made taboo as they are in many religions), the third source – death throes - is unnecessary.
The fact of the matter is that if the "magician is worthy of his name, he will be uninhibited enough to release the necessary force from his own body, instead of from an unwilling and undeserving victim! (The Satanic Bible, p. 87)
Symbolic Sacrifice As Source of Wrath:
The only people Satanists will consider targeting with such a sacrificial hex is a "totally noxious and deserving individual" who "by his reprehensible behavior, practically cries out to be destroyed." (pp. 88, 89-90)
In fact, Satanists see the elimination of such obnoxious influences as something of a duty. These people are emotional leeches, dragging everyone else down to feed their starved egos. Moreover, Satanists stress responsibility for behavior. Actions have consequences. When people behave badly, their victims should take steps so as not to be further subjugated to the abuse rather than turning the other cheek and making excuses for the offender. As the eleventh rule of the Eleven Satanic Rules of the Earth states, "When walking in open territory, bother no one. If someone bothers you, ask him to stop. If he does not stop, destroy him."
The target should never be undeserving of it. Regardless what urban legend might say, Satanists have no interest in targeting virgins, holy people, or any other upright members of society. Nor is a target ever chosen at random. To do so would be both malicious (not to mention sociopathic) and lacking in the desired anger.
In addition, both animals and children are specifically forbidden targets. Both lack the capacity and understanding to bring such a consequence upon them. Animals work on instinct, and maliciousness operates on a level beyond instinct. Children are held particularly sacred to Satanists, and they consider any harm visited upon them to be particularly vile.
