I see your point, but I also don't see much of a leap.

If 90% who survived suicide did not attempt suicide again it sort of does suggest that had more people survived their suicide impulses they would also be one-timers. Sadly, sometimes one impulse is the last.

I read about bridge jumpers who survived (I think it was the Golden Gate Bridge, FWIW) and most said the instant they left the bridge they had a rush of clarity and profoundly regretted what they had just done.

Haunts me still to think about the ones that didn't survive but likely had that same moment of horror.
