My stance is pro-life.
There have been many people who have attempted suicide, and failed. Many of them see it as a new chance at bettering themselves and their lives. Not everyone, but many. Many people also, in the process of their suicide attempt, realize they feel ambivalent about dying.
If someone is truly suicidal, they will do it without any hesitation at all--right to the very end.
I believe that humans have inherent worth and that our decisions matter. It matters whether we live or die.
I wager that most people who are suicidal are because of deep emotional and/or physical/spiritual pain, and a sense of hopelessness. I'm not convinced that someone who is deeply suicidal/depressed is in a clear enough state of mind to make such a decision as to end their life. I say this as someone who has been deeply suicidal and depressed. If I were to go through that again, I would hope that I realize that I am not thinking logically or rationally, and that it is an emotional state is clouding my decision-making process. It is not so simple, of course, because it can be really hard to go from zero to one, then two, and then three.
But we must try to get from zero to one. Once you get to one, it gets easier to get to two. And then to three.
Getting to one is better than staying at zero.
There's the possibility of getting to one. There's the possibility of things getting better. To what extent can we trust our feelings of hopelessness and desperation to recognize this?
