Great comment and thanks for dropping by.

If the individual has explored all possibilities and their resulting probabilities, and suicide still comes up at the top of the best courses of action, would it not be selfish to attempt to prevent such proceedings. Thusly, creating a larger imbalance in the equilibrium of the universe.

Humans are intelligent and thus they have found ways to circumvent death even when that is the path that nature has laid out for them.
In some ways suicide can be considered a balancing act, as we continue to overpopulate the planet.

Though I say this, after enduring my own personal hell for decades, I can give those who contemplate such actions, the notion that maybe, just maybe, there is a reason that they are going through their experience. Sometimes you need a little faith in yourself and the universe, and it will deliver.

Life throws a lot of questions in front of you, but that doesn't mean you will find the answer to all of them before our short time on earth runs out. I think that this uncertainty contributes to rise in suicide; when the time and the universe both don't have the answer, then we create our own.
