Annie Lennox and The High Priestess
As noted by many others, Tarot cards are not inherently evil: they are neutral. It is the intention and use of the cards that determines if their use is good or evil.
For the context and possible meanings of these images, the reader may wish to familiarize themselves with Gematria.
Whether or not you believe in this does not matter. “They” do and to them it is everything.
