I Ain't Got Time To Bleed (1999)
Context: I'm not disparaging suicides when I call them weak, I'm pointing out that anybody who would consider doing a thing like that needs help. I don't think a normal, mentally healthy person commits suicide. Of course, there are exceptions; people who are terminally ill are a different issue. But in the vast majority of cases, suicide is a tragedy that does unbelievable damage to the family and friends the suicide leaves behind. You don't want to encourage people to do such a thing.

To Leon Goldensohn, February 12, 1946, from "The Nuremberg Interviews" by Leon Goldensohn, Robert Gellately - History - 2004
