Looking at it from an fourth dimensional point of view, tempting fate would be bending it, therefore fate isn't the correct term for it. It would just be not beleiving in it at all.

Also, if you think of the world as a university for the souls that want to learn about what happens in life, from a different society or world it would make more sense, considering it is for learning purposes. The nature is the preset of the education, and the humans are the learning resources, since the nature really has nothing too big of a flaw to start with. Humans on the other hand just ruin things, there isn't too much they can do to reperfect nature in it's state now.

And if you look at it that way, fate could be possible; also considering if everyone around you are a phantasm, and you yourself are invincible. (i.e. Pulling the trigger on your head; gun jams) The phantasms around you are just preinstated clients from the other living beings that are living in their own dimension. There are lots of theories, those are just mine. And looking at it from the human's capacity for psychological balance there will never be a way to find out. And the safest path to take is to not beleive in fate because that could be dangerous mentally.
