Reincarnation: Is there an advantage for non-believers?

[Tenet Nosce]

Why did all this happen this way? Because that's the way we all wrote this story.

P.S. People don't necessarily keep coming back as Christians, do they? They could come back as anything.

Yes, but the notion that reincarnation doesn't exist has little, if anything, to do with the teachings of Jesus.

I still don't seem to be communicating the question clearly enough. There is no "attack" here on Christianity.

Anyway, forget about Christianity. Let's just talk reincarnation.

Why would an entity program an incarnation to have a belief that this is their "one and only" shot at physical life? Is there some advantage to this?
