In "The Crucible," Tituba is a black slave from Barbados. Tituba realizes that because she was with the girls in the woods during the alleged night of dealings with the devil, she is a suspect. Her second class, or worse, status as a slave does not help matters since the very fact of her social position as a slave indicates the town's racist practices and therefore, an unfair assessment of Tituba's intentions and virtues. Also, the history of Voodoo in Tituba's native Barbados does not help when the accusations of witchcraft begin. Overall, Tituba is presented as a character readers would sympathize with.
Following the narrative which precedes the play, Miller sets the stage for the first act and describes Tituba's mental state:
She enters as one does who can no longer bear to be barred from the sight of her beloved, but she is also frightened because her slave sense has warned her that, as always, trouble in this house eventually lands on her back.
Tituba is devoted to Betty so she is genuinely concerned, but Tituba is being cautious because she knows the possibility that the town will make her (Tituba) the scapegoat just because of her ethnic background.
However, as sympathetic as Tituba is, she does eventually break when threatened by Abigail and Hale. At the end of Act 1, Tituba breaks and accuses Sarah Good and Goody Osburn. Tituba claims the devil spoke to her:
And I say, You lie, Devil, you lie!" And then he come one stormy night to me, and he say, "Look! I have white people belong to me." And I look--and there was Goody Good.
Even though Tituba makes false accusations, she is still somewhat sympathetic because of all the characters in the play, she has the lowest social position and is therefore, the easiest and most likely to be bullied and pressured into doing or saying something against her will.
