Hmm...most of the time it happens when one cannot see or bear to
live tomorrow's life with their current sadness/depression.
Sometimes, it happens when people watched too much movies and they
subconsciously reacted to this form of behaviour to appease their
own sadness/depression. But, nobody will have the courage to
actually kill themselves unless they are already at their most
desperate ends of their mind, and sometimes they preferred to kill
others if they do not have the courage to take their own
life.
Yes, it's true that everyone has their own limitations to their own
sadness/depression. Everyone has their own sad experiences in their
lives that they cannot overcome the grief with and still griefing
over it. And this is the cracking point that they don't allow
anyone to make fun of or criticised or reminded of. And nobody
should ever even try to find out each other's cracking point and
take advantage of it. Unfortunately, in this world...there are alot
of sick people around us that will not hesitate to take advantage
of each other's weakness to lord over each other. To be frank, this
includes a lot of people in our lives including those we grew up
with, friends, colleagues, and even people very close to us. So
beware and never trust your cracking point to anyone but
yourself...unless you have confidence in that person. And never to
trust those to whatever counsellers or psychiatrics or social
workers, cos even if they're trained to advise and absorb and work
in that line of field, cos ultimately they're STRANGERS.
Taking own life is never the ultimate solution to any
trouble/situation/sadness/depression, it is just the best way of
escape from life itself. It requires more courage to wake up
everyday and face the life in our future than to end it all within
20 seconds. (Heard that a person still possess 20 seconds of
consciousness before going to see their maker 
)
Funny thing is, people never die for themselves. Examples like
dying for love, money, work, school, pets. So think first before
you really take your life, cos you could easily laugh it off and
live another day. When you think that all hopes in this world has
failed you, the remaining uncertaincies that you haven't thought of
will definitely overwhelm it and you will begin to see life after
it if you just hold onto life itself for one more day.
Good luck all, take care and have alot of fun being alive.
