Devil Worshiper
Considering how you interpret the term...
Wouldn't saying that life is worth living, as a definitive fact, to someone that is about to suicide, trying therefore to convince them to don't kill themselves count as proselytism?
Sort of. It's normally not a very useful way to talk somebody down from suicide, in my experience, precisely because it's taken as preachy and taking too definitive of a stance on their experiences. Mental illness affects everyone differently, I don't think that's a universal rule, but I've never met somebody on suicide watch that wanted to be told that life is worth living. There probably are a few, of course; I've just never met them.
Most of the ones I've spoken to often already think life is worth living, but are having a hard time coping with living it and fall into understandable fatalism through their failures, low self-esteem, anxieties, etc. Sometimes telling them that life is worth living might, paradoxically, stress them out more and be counter-productive. You really have to listen to somebody on that edge carefully and I think proselyting is probably the last technique you would want to try.
I had a conversation with a hostage negotiator awhile back and they said the same general rule applies there, too.
I know that's sort of tangential, but I thought it was important to note.
