I definitely think certain factors make us more prone to do certain things. However- let's say you're right and many of us here are predestined to CTB. All of our shitty life circumstances have culminated in this inevitable act.
So, why will likely the majority of us not commit today? (I imagine.) Because we choose not to. We don't like the prospects of success maybe with the methods we have to hand. Maybe fear holds us back. It's still a choice though- ultimately. Maybe later down the line, we will make the choice to do it.
Some people will also argue that other people could indeed 'save' them. So, are they destined to be 'saved' and recover or, do they only have more potential for it? What if they could be saved but, no one bothers? Again, it's likely the sum of their experiences that determines whether they can be helped but- how do we differentiate?
Surely again- it comes down to choice. We ask the person or, we provide services they can reach out to for help. To allow them to choose.
Simply looking at someone though, how can we know whether they are destined for suicide or, destined to recover? So, how do we know who to help and, who to leave alone? If they want to be left alone that is.
Have you seen the HBO series: Westworld? In the third series, there is a massive AI that predicts a person's future, given their past.
Spoiler alert here: One of the main characters has a very tough childhood. His mother is mentally unstable and abandons him. He goes through something massively traumatic in the military. Therefore, it's predicted his life will end early via suicide. Because of that, the system holds him back in terms of career progression. Why invest in someone who will take their own life?
The worry I have with the idea of predestiny- especially if we predict only bad things is- I wonder if it's a self fulfilling prophecy. If we've decided we'll fail at whatever we do. That we have no chance. That it's inebitable we'll do or not do something, will we even try to create a different outcome?
Where I do agree is- so much shit can happen to us in life. People can end up living such incredibly hard lives. So- yes, sometimes we're so stuck that our loved ones won't be able to help us anymore. Even if they want to. In which case, I do absolutely agree. I wish they could accept that they couldn't have done more. The person was stuck in their suffering and only wanted out- which seems reasonable.
