Don't you believe that such cases exist? Presumably there are also people who want to die, no matter what. But there are also people who just go through periods of depression. I also had the issue as a youth. It sounds to me as if you are hellbent on denying the OP's point by pointing to the extreme examples of suicidal people. What's wrong with trying to save at least the people who may only have a temporary attack of suicidal thoughts?

It only takes a fraction of a second to pull the trigger, if a gun is at hand, or to jump off a bridge. Then you can't reconsider anymore.

I'm in sympathy with the OP's post (the one with the DFW quote). The post I was responding to, seemed to suggest that people who are suicidal should generally not be taken seriously - that they arrived to their ideations by delusion - without acknowledging the other possibility.

I'm positing a counter-claim that not all people that are suicidal are also irrational, and I provided one example that I don't think so extreme, that was referenced in the OP's post. Robin William's case is another example though his decision was spurred by physical ailment[0]. Keith Flint (singer of the Prodigy) is a better example, he claimed his own death to be 'a positive thing'[1] (have no special love for the band, just a good example)

These examples could be outliers, I don't deny the possibility, but I must at least acknowledge that they exist - which was my whole point. I'd go further to say that we under-estimate how many people are both suicidal and rational.
