Do you believe by the end of my class that I can convince you to kill one another?

The students laughed at the teacher. There’s no way. They’re smarter than that and besides, they’re classmates. What would make them want to do that?

The high school teacher now had something to prove. He wanted to teach the students that human psychology works in mysterious ways. By the end of his course, he would prove to lead his entire class, brainwash an entire town, and even have people die for him. 

Think you’d never fall for it? Think again.
