It's not a matter of whether Fujisaki-kun was entitled to one in the first place - it's that he received one anyway, only to have it taken away from him. Given that my brother and I both have death waiting for us back home as well, a possible interpretation that can be taken from that is that whoever brought us here thinks that we deserve the second chance more than Fujisaki-kun does.

That's the rationale he's following, Kirigiri-kun.
