The ending is effective because it gives the reader the choice. It sparks conversation and forces the reader or group to analyze and really think about the story so they can decide how it ends.
The central idea of Mike kubick's article 'The salem (and other) witch hunts' was to show how people, mainly women, were chased by the Church and obliged to confess crimes they hadn't committed. All this hunt was made 'in the name of God' and it was very difficult to escape or to think about denouncing the problem to authorities since they were the same people that committed such an abominable act.
It’s operation. Hope this helps
