The way that I see it, why is it anything to do with us if people decide to ctb, it's not our existence, the reality is that the right to take control over our inevitable fate is a basic human right as without that existence is no different to slavery, it's inhumane to want to trap people in existence and imprison them against their wishes. The potential for the most extreme suffering will always exist as long as one is trapped in this harmful world which is why to me wishing to cease existing will always feel like the most logical option and even if there wasn't extreme suffering nobody is obligated to continue existing anyway. When to leave this world is a completely personal decision after all that can only be made by the individual.
There is no point to existing, why should anyone have to continue this involuntary experience if they don't wish to, we only exist because some people were selfish enough to unnecessarily force life here, there is no meaning to life other than it being a tragic consequence of evolution and anyway we are all destined to die, it doesn't make much difference if someone dies now or in 50 years at the end of the day other than all future suffering would have been prevented and I personally always see it as being preferable to cease existing as existing here is something completely unappealing and futile, I would rather avoid all future harms and I know that I've existed for far too long.
I'm 22 now and I wish that I left when I was much younger, as the longer spent here the more meaningless, unnecessary suffering experienced all for the sake of it. I admire those with the courage to take control over their inevitable fate, freeing themselves from this burden, to me the thought of not existing forever with all problems solved and everything finally forgotten about is so beautiful but in reality the best outcome is never existing at all as then nobody would have to die. I see nothing more ideal than not existing which is why suicide is self care to me, life itself really is the true problem.
