This subject has been on my mind quite a lot recently. One thing that worries me in this criticism is the scant attention paid to the possibility that people are drawn to suicide not necessarily because they are 'messed up' but because of physiological and chemical imbalances in the body. I know this because following dental work (amalgam removal) I suffered from very strange suicidal days and black depressions which are totally out of my normal character. I have been in touch with many people on the net in the search for cures for illness who make this close connection between body chemistry and suicidal tendencies.
