"By [Japanese] tradition, suicide can absolve guilt and cancel debt, can restore honor and prove loyalty. 'The heirs of Cain can never escape the eyes of God, even less in the next world than in this,' Maurice Pinguet wrote in his study 'Voluntary Death in Japan.' 'But in Japan you can hide in death, disappear into it entirely and mend the fault as you go' In Japan, suicide can be a gesture of moral integrity and freedom, or an act of beauty."
