I agree with this for the most part.
One of my closest friends killed themselves. It was decades ago now, but they never, ever gave any hint that they were feeling low, had ideation, there was no interaction or history with mental health services, nothing at all that could have even so much as hinted at what they were planning to do. It obviously devastated their family, and I've seen how it has changed and affected them as people due to staying in touch with them down the years. I can relate in some way to them because it seriously affected me for a long time before I was really able to process it. I've also lost a close family member to accident who was around the same age as my friend, and in truth the effect on their family is much the same.
You can say "well there was no need for friend to take their own life", and that is true, but there was also no need for my family member to be doing the activity they were that caused the accident that killed them.
I've had periods of really poor mental health in my life where suicidal ideation was a constant theme, and to be perfectly honest, even given what I know about how death affected both families, the thought of how mine would react if I had acted on the ideation never, ever entered my mind. It simply isn't a consideration, and I don't see why it should be given that my life is not theirs to decide what to do with.
I work in mental health, I am trained in mental health first-aid, part of which means dealing appropriately with people who are clearly in crisis and may be at the point where they are either planning, or in the act of attempting suicide. While I would always do everything I could to discourage, protect, and help them, I'm of a mind that if someone is so genuinely bereft of any desire to live that they want to die, then nobody has any right to judge them for acting on that. I think that if my friend was so desperately unhappy that they felt the need to do what they did, then I'm happy for them that the suffering ended for them as soon as they went through with the act.
Of course I wonder if they may have felt differently later in their life had they lived, and perhaps at some future point they'd have been glad to have not gone through with their plan, but it's also possible that may never have been the case, which is why I've never been able to feel any anger towards them, or felt it in any away appropriate to judge them for what they did.
