Major plothole
I hate posts that start with that tagline: Major Plothole - 9 out of 10 times, it not even a plot hole. I think though, I have found a pretty large discrepancy with logic:
We are told that killing the last "Gabe", will make the remaining survivor a god - or the collapse of reality.
No wonder, this is a priority. So we hunt them down and in the end, we have both of them. yoo-hoo.
One we send to a prison planet, where his chances of surviving are slim. It is pretty much a death sentence.
And the other we send to a planet to find his own destiny - in fact, the authorities planned to send him back to an almost guaranteed death penalty, had Funch not gambled.
So, the two people whose deaths could destroy us all, we send off the places where we cannot protect them. And to places that are pretty much aimed at killing them.... in other words, the one thing the whole movie was trying to avoid.
... now I get the title ;)
