You have no idea what leads a person to suicide in every single case, so it's judgmental to call them "irrational". Every suicide case can somehow be rationalized, because let's face it, life sucks for most of us, especially in this pandemic and economic situation, we're still gonna die, most likely having no enjoyable leisure time or retirement, so what's the fucking point? The future is never pleasant, it's wrinkles, disease, pain, and loneliness, no matter who you are. You have no right to tell someone who wants to end their horrific pain forever not to do it, stopping them becomes a form of torture.
