Why is tituba’s prayer an example of dramatic irony?

Tituba's prayer is an example of dramatic irony because she prays to God only to show off to the people.

EXPLANATION:

Dramatic irony occurs in a play when the audience knows the situation in the play and understands it, but the character doesn't understand the same. The words and the actions of the characters are often contradictory in this case. Tituba is a woman from Barbados who does black magic and she prays to God just to show to the people about her believes in God and is on God's side. But she was the one who did black magic, planned the dance in the forest and conjured the bad souls. Thus, her act is an example of dramatic irony.
