say, I was walking with a friend, crossing the road. suddenly, out of nowhere this vehicle comes speeding down the road, towards us. My friend pushes me away, to save me. And I think, no! So I rush ahead and push my friend away instead, and I stand in the path of death. Then, maybe I actually have some time! I can quickly jump off or something, and maybe get my leg hit, or save myself altogether. BUT maybe, I will stay put, look at the oncoming crazed vehicle, and await death. So that it can relieve me of the burdens of living, of the thousand-and-one things I have to do, of the thousand-and-one things I have to worry about.
But also MAYBE, by some divine intervention, the vehicle manages to stop, barely missing me by an inch. And I have to go on living this wretched life. And that would most likely happen.
I will be sorry, too. because I tried to selfishly end my own life, leaving that poor friend behind to witness a gruesome death, an image that may remain in his/her mind forever.
