Destiny

Sorry,but I must disagree.I don’t believe there is a ”destiny” or ”fate” concerning suicide.Yes,we’re all destined to die,but we’re not destined to kill ourselves.We are responsible for our actions and interactions.Suicide is a choice,not something dictated by fate,nature or some divine being.When someone kills himself/herself,he/she does that by having full consciousness of what he/she is doing.Even animals can choose to kill themselves (I’m copy-pasting from wikipedia’s article on animal suicide):
Many animals that appear to be depressed or grieving begin to exhibit self-destructive behavior that sometimes ends in death. In 1845, the Illustrated London News reported that a Newfoundland dog had been acting less lively over a period of days before being seen “to throw himself in the water and endeavor to sink by preserving perfect stillness of the legs and feet”. Every time he was rescued he attempted to do this again before he finally held his head underwater until death. Other dogs, as well as ducks, have also drowned themselves. One duck did so after the death of its mate. Some dogs will refuse food after the death of their owner until they die as well.
The dog,for example,that its owner dies,sees its world collapsing and loses every reason to live (or so it believes).Then,it tries to stop living.That’s a choice that it makes,nobody forces it to die.It could choose to continue living and find a new owner.That goes also for humans.We are,after all,animals too.Our main difference with other animals is that have an evolved mind, a mind that is more aware of our actions.Suicide derives from a logical process that isn’t based in (what is called) rationalism.
