Seppuku: Before watching the video here's a quick definition of Seppuku: In feudal Japan, Seppuku was a ritual suicide practiced by the samurai. It was performed as an act of honour to restore a person's dignity after disgrace to failure. It may seem harsh to humanity today as the way we live nowadays but back then in the samurai culture honour was considered a big part of life which one had to be upheld at any costs.
