South Koreans and Japanese need a tougher attitude when it comes to parents who take the lives of their children when they commit suicide, a South Korean expert on suicide prevention says.

In an interview earlier this week, Han Sang Yup, director of the South Korean branch of Befrienders International, said he believes cultural inclinations may make South Koreans and Japanese more tolerant toward suicide than are Westerners.

Still, he said, this cannot justify an act he calls murder.
