Love is one of the most intense feelings felt by man; another is hate. Forcing yourself to feel indiscriminate love is very unnatural. If you try to love everyone you only lessen your feelings for those who deserve your love. Repressed hatred can lead to many physical and emotional aliments. By learning to release your hatred towards those who deserve it, you cleanse yourself of these malignant emotions and need not take your pent-up hatred out on your loved ones.
― Anton Szandor LaVey, The Satanic Bible
