Final answer:
During the Salem witch trials, Ann Foster was one such individual who played both the roles of accuser and accused.
Step-by-step explanation:
During the Salem witch trials in the late 17th century, there is at least one known case of an individual who was both an accuser and later accused of witchcraft. Her name was Ann Foster, who initially testified against others and later found herself accused as well. This shift in roles can be attributed to the hysteria and fear that surrounded the witch trials. Accusers were often motivated by their own fears and beliefs, but once they themselves became targets, they may have realized the injustice of the accusations and the flawed nature of the trials.
