On March 20, 1995, members of the Japanese religious sect Aum Shinrikyo released sarin gas, a nerve agent, on several lines of the Tokyo Metro system in five coordinated attacks, killing 12 and injuring thousands. Carrying homemade liquid sarin packaged in plastic bags, the perpetrators boarded the trains, punctured the packets, and left them to vaporize on the car floors. More than 10 Aum members were sentenced to death for their involvement in the incident. What was the group's motive?
