When Reverend Sykes closes the door to the church and doesn't let anyone out until the right amount of money is raised for Helen Robinson, what is the main idea we are supposed to get from that?

He is an authoritarian preacher who is used to getting his way, no matter what

He is a pragmatic leader who isn't afraid to make his congregation do the right thing

He understands that people will only do what they are forced to do, rather than what they want to do

He knows that people don't want to help Helen because of the charges against Tom
