Looking for philosophical and/or religious perspectives (if allowed):
Let's say you have a machine that predicted, with absolute certainty, that I would be killed in a car accident if I drove my own car home from work this evening (further, let's say this is through no fault of my own; I just happened to be in the wrong place at the wrong time). You did the neighborly thing, and told me well in advance.
So now I have knowledge and options to avoid that fate: I can get a ride, call a cab, sleep in the office, drive somewhere else, etc. And let's say that I'm not saving anyone or helping anyone demonstrably by being in this accident (so there's no incentive for sacrifice), so the only person who benefits, it would seem, from avoiding the accident is me. If I choose to drive myself home in my car anyway, is this tantamount to suicide?
