Evidence that a reputation for black magic (and rape) could get you killed. John Lambe was an alleged English sorcerer who was murdered by a mob.

From Wikipedia:

“John Lambe (or Lamb) (c. 1545 – 13 June 1628) was an English astrologer who served George Villiers, 1st Duke of Buckingham, during the early 17th century. Accused of black magic and rape, he was stoned to death by an unruly mob in London.”

(Although John Dee was a person of significance in Elizabethan England, he also had a tentative reputation as a sorcerer, and was at times in his life fearful of the consequences and actively fought against libels which could have cost him his life.)
