Please don't overanalyze this. You have to sacrifice one to save the other.
You don't kill anyone with your own hands. The stranger isn't related to you in any way.
If you forgo any decision-making, they both die.
If you have multiple pets, the pet in question is whichever you're most attached to; if you're equally attached to all of them, it's a random draw.
