So, what am I -- the Delphic oracle? I won't say I don't know anything, but I don't know much, except that the love and mercy of God are extraordinary. I do know that God not only makes the trees, but He personally draws forth each leaf. (If I get to know you better, maybe I'll explain how I know that -- in any case, you don't have to believe it; I am utterly convinced of it.)
Suicide is a terrible thing. As Chesterton said, "The man who kills a man kills one man; the man who kills himself kills all men." He thinks the instinct of the Church to bury the suicide at a crossroads and not in consecrated ground is a true one, but he recognizes the sad and tragic apparent motivation behind most suicides. I would doubt that any suicide acts with "full knowledge and full consent of the will."
