Final answer:
A different decision by John Proctor in 'The Crucible' could have spared the community from further hysteria.
Step-by-step explanation:
A potential effect of a different decision by John Proctor at the end of the play 'The Crucible' could be that the community would have been spared from further hysteria.
In the play, Proctor ultimately chooses to confess to adultery, a false crime, in order to protect his wife and preserve his reputation, even though it means signing a false confession and losing his life. If Proctor had made a different decision and refused to confess, it would have demonstrated to the community that the witch trials were based on lies and manipulation. This could have led to a loss of faith in the court and put an end to the hysteria.
