Why does Tituba admit to being a witch?

Tituba admits to being a witch primarily because she is coerced into making this confession to save her own life. The intense pressure and fear imposed by the court and the community during the Salem witch trials create an environment where she feels that confessing is her only option for survival. By admitting to witchcraft, she hopes to avoid the dire consequences that accompany being accused, such as execution. This decision highlights the desperation and systemic fear that characterize the atmosphere of the trials, where individuals are often left with the choice of either confessing to something they did not commit or facing severe punishment.

While other options present interesting ideas about her motivations, like proving innocence or accusing others, they do not accurately reflect her main reason for confession within the context of the story. Tituba's acknowledgment of witchcraft serves as a stark illustration of how societal pressures can lead individuals to betray their own beliefs and truth in the face of grave danger.
