Erm, this is kind of off-topic, but I'd like to argue that staying alive while having suicidal tendencies is actually beneficial to the species, and to the human condition. I know this sounds trivial, but bear with me here for a second.
First of all, as long as one exists, one will influence their surroundings, voluntarily or not. This increases the overall diversity of the system, because when units that "are not supposed to be alive" exist nevertheless, they generate variables that would otherwise not appear in the system, because they would disappear with the unit's self-extermination.
The ones that don't die and we get to hear about, usually dwell in the humanist arts. Artists, musicians, writers. Beksinsky is probably one of the more significant contemporary examples of that, and so was his son. Read up his bio, it's a miracle this dude was alive by his 40's without landing in a nuthouse from all the stress, both self imposed, and external (such as constant fear for the life of his son).
Personally, I learned that I had several people like this in my surroundings that shaped my identity and personality. I'd be a totally different person without them, and I feel like there would be "less of me" without the influence of their uncommon outlook on reality. I do realize this is a purely egocentric approach, but, if, say, P.K.D ick
[1] made it on the 23rd of March, 1972, we wouldn't get A Scanner Darkly. And he wouldn't get to meet Ridley Scott, and see the preliminary visuals and sfx shots for Bladerunner (which he liked a lot, and said it was exactly as he envisioned them)
Second of all, we are all mostly a product of our circumstances. Our upbringing and conditioning determines our future to a high degree. Our power to influence the world, our surroudings, and other people, or lack of thereof, is a result of many variables that we cannot change for the most part of our lives - like having rich or poor parents. We can, however, influence ourselves. In our species, the brains retain neuroplasticity throughout a significant portion of our lives. Neural networks are exceedingly good at adaptation to weird or uncommon circumstances. Constant suffering or unwillingness to exist, without malevolence towards the rest of the specie, from my observation, creates very interesting individuals. In b4 Harlan Ellison,
I have no mouth and I must screamThird of all, and this is from my own experience, we should avoid irreversible decisions, or minimize their impact. We're all really future-stupid, and most of our decisions, even the significant ones, are dictated by really trivial stuff - like our semantic layer, our expectations, and overall subjective interpretation of surrounding reality. Our suffering is largely subjective as well.
Hell is just a frame of mind - know this one? It's from the 16th century. Christopher Marlowe,
The Tragical History of the Life and Death of Doctor Faustus. In b4 Byron, in b4 Shakespeare, in b4 Poe. Seriously, people struggled with their own existence for centuries, it's nothing special, and you're not supposed to do anything about it. Keep calm, increase entropy, suffer till the end.
I'll end this with a quote from Lem:
for moral reasons ... the world appears to me to be put together in such a painful way that I prefer to believe that it was not created ... intentionally
[1] Seriously? You can't write D*ck without it getting starred out? SERIOUSLY?

You do x, sine goes to 1, you do h, sine goes to 0, you do j, sine goes to -1.
I like this metaphor for some reason :3
