You should care for the same reason you don’t want to die—not because being dead is so bad, but because you’d rather be living.
If you play russian roulette with a quantum coin, “you” don’t move into a different world if the gun fires. There is no immortal soul that occupies quantum states like a hermit crab, scuttling off into a different sized shell when necessary. If you don’t like dying, you won’t like getting shot.
It’s possible to construct an agent that rationally chooses quantum suicide. But this is inconsistent with not wanting to die.
