Wanting to die (or 'suicidal ideation'as the experts would have it) goes hand in hand with the illness. It is a symptom of severe depression, not a character failing or moral flaw. Nor is it, truly, a desire to die so much as a fervent wish not to go on living. All depressives understand that distinction.
