Present the standard Trolley Problem scenario: a runaway trolley is heading for five people; you can pull a lever to switch it to a track where it will kill one person. Analyze the 'right' action from a Utilitarian perspective (maximizing good) versus a Deontological perspective (duty and rules). Then, introduce the 'Fat Man' variation (pushing a man off a bridge to stop the trolley) and discuss why the moral intuition often shifts despite similar outcomes.
