It, unfortunately, has "Reasons" & "Methods" before "Prevention" and has no mention of why you shouldn't commit suicide.
At the bottom of the first page of the results, the first related search is "suicide methods" (http://imgur.com/7lJ02)
Further search for "suicide methods" results in the following first three links:
http://en.wikipedia.org/wiki/Suicide_methods
http://wantdeath.blogspot.in/2011/07/fastest-and-painless-suicide-method.html
and
http://frater.com/suicidelist.html
There is no mention of why suicide is bad and it just gives the depressed person a way to end his/her life.
Sometimes these links are enough to push people over the edge.
I don't blame only Google, but I think the entire web & the web community (with SEO, SEM, Wikipedia edits, etc) contribute a lot for this disaster.
Is there a solution that you can suggest?
