One morning a Japanese farmer sees his deranged wife trying to hang herself. Rushing to her side he manages to calm her down. But the moment his back is turned, she again tries to kill herself. Struggling to control her, he slams her against a wall. She sustains head injuries and dies.
In most societies, this man would spend years behind bars. That, however, was not the outcome.
Although the farmer admitted that while struggling with his wife he thought how he would be free of her if she died, the public prosecutor eventually moved to suspend prosecution.
