I mean we make an attempt to stop most suicides on the basis that they’re pursued from a kind of irrational train of thought. This isn’t to say that that’s always actually the case, but we can’t be sure of that, so most people wouldn’t look at a guy jumping of a bridge and then say “hey do a flip on the way down”, you know? We can kind of assume it’s more of a last resort, than like a casual pastime or decision that you might just kinda make cause you kinda felt like it. That’s just talking about the psychology of people who try to kill themselves mostly, though, for the vast majority it’s as a last resort rather than due to a more “rational” reason, or, a more philosophically motivated reason.

It’s a much safer assumption to assume they’re irrational, anyways, for the same reason that capital punishment is not really a great idea. If you take the opposite as a blanket decision, it’s irreversible. If you put out someone who’s on fire, or otherwise save someone who’s suicidal. you could always just kill them later.
