Making such generalisations is dangerous; for example, suicide when one is terminally ill and in terrible pain could be seen by many as the sensible thing to do.
Yes I agree there may be times where suicide seems preferable to life in the cases you mentioned.
My issue is with this article As far as I can tell this man wasn't definitely depressed. It seems he was just unhappy with his situation and chose to take the easy way out.
There are others who have committed suicide at that factory but of course they aren't poets...
Since he took the rather bold step of actually ending his own life I would think that his outlook on life was sufficiently bleak to warrant at more empathy than that.
Regardless of if he was clinically depressed or just very unhappy, are both not tragic?
Please re-read his words and decide again if his plight was shallow-hearted.
