Analyze the classic Trolley Problem: A runaway trolley is heading for five people. You can pull a lever to switch it to a track where it will kill only one person. Then, consider the 'Fat Man' variation: You can push a large man off a bridge to stop the trolley and save the five, killing him. Discuss why many people make different choices in these two scenarios despite the mathematical outcome (5 lives saved, 1 lost) being identical. Evaluate whether Utilitarianism provides a consistent answer to both.
