This interactive simulation presents the Footbridge variant of the Trolley Problem (Play the interactive Trolley Problem). Unlike the classic lever version, this scenario requires direct physical action: pushing a man off a bridge to stop a runaway trolley. This adaptation highlights the moral tension between actively causing harm to one person versus passively allowing harm to come to five others.
