Milgram experiment

I was baffled to see how 65% of the people continued the experiment to lethal voltage. I was surprised to see how they did not listen to their morals and conscience just because someone in authority told them to continue.  These leads me to the question whether the people were free or not to stop the experiment and not continue just because they were told to.  Based on the Agency Theory people are free in their actions. They weren't bound by destiny to continue but could have stopped and started a new chain of events by not continuing. Also the people acting as prison guards could have stopped and quit the experiment.  They were free in doing this, however they let their environment and setting influence them. However, based on the agency theory, the prison guards could have listened to their morals and didn't have to do the experiment. The agency theory states that we can make decisions and perform actions and start new chain of event. It was the peoples' choice to listen to their instructions and perform what they felt was contrary to their morals or to not do the experiment. Based on the agency theory they could have done the experiment, creating that event, or they could have decided to quit the experiment and create that event. The agency theory agrees with universal casualty in how one event was caused by another which was caused by one before that and so forth. However, the agency theory states that people can cause events to happen. We, the agents, can cause a new tree of events to happen. According to the agency theory people can cause events to occur.  It was up to the people to choose whether to continue or not. Based on the agency theory they had freewill.
