Cmv: i don't think every suicidal person can be helped and some are "better off" gone.:
This isn't referring to depression because of a terminal illness, but specifically about clinical depression prompting suicidal urges for years. Decades even.

I don't view suicide as a choice - it's a fight or flight response. Some people cope others don't. 

Also my philosophy on the value of life undoubtedly skews my stance. I don't believe that anyone has an objective, inherent value and that disallowing someone to end their life promotes their suffering for the comfort of society being uncomfortable with death. 

However, temporary bouts of suicidal behavior should be treated but at a certain point it becomes so chronic that pain overshadows pleasure.  When someone has suffered for years with suicide but have held off because of guilt from family they are literally tortured into accepting life rather than be allowed to bow out peacefully.
