Bit of a thread bump here, but...
According to the Stoics it would be a wrong reason if one attempts suicide simply because of unhappiness with ones own life circumstances. Rather, one should see them as a challenge to test the virtues against. I feel it's important to add this context when using an ancient quote.
This sounds like a very rational approach. Interesting that such a perspective would be essentially banned in modern day discourse.
Choice is extremely fundamental to life, and we must accept that everyone will make choices of their own accord. Anti-choice is an illusion; at most, it is possible to add barriers.
Suicide is unique in that there is no Ctrl-Z option. Even so, it can be treated as a noble act of martyrdom, an act of vengeance, or something between. Personally, I lean towards the nobility side, including accepting my inability to meaningfully help others and a desire to give away all my possessions, including the body itself, to others. And yet, the act itself is identical to another person coming from a place of apathy. The place where we are coming from in the act of suicide is therefore a choice within a choice.
