A complex phrase that warns against codependency. "Psychic vampires" are people who drain your energy, time, and resources through constant neediness. This frase teaches that a Satanist owes nothing to those who refuse to help themselves. Charity is a transaction, not a duty.
The most popular phrases shared on social media often come from The Book of Satan (the first book in the text). These phrases champion the ego and reject altruism that is forced or fake.
This is not a call to be a monster. It is a statement of realism. LaVey wrote during the Vietnam War, the Cold War, and civil unrest. He believed that pretending humanity is "good" is naive. Therefore, the Satanist arms themselves with cunning, deception when necessary, and a steel spine. The "cruelty" refers to the truth, not the action.
