I actually read the protagonist as ‘probably suffering from radiation poisoning, might be about to literally die from the next bomb or the building collapsing’ as of the moment before they hit the reset, so I would see such planning as irrational rather than sensible—a little information might help, but not if it risks your life (which is what you’re thinking about if you’re selfish) or the fate of the world (which is what you’re thinking about if you’re selfless).
