No. I have no emotional connection to this stranger.
Because I have no emotional connection I feel no protective urges for this person.
Therefore they could die and I doubt I would lose much sleep over it.
If that was the ultimatum, me or them, than I think self preservation would win over.
Just a random stranger? No, I don't know them at all so there's no emotional ties to take in consideration. Instead it's just some dude and I generally value my life over the life of some random person I've just met.
Just one stranger? No. In that case, one person will live, it might as well be me (the other person could be a serial killer for all I know). 10 people? I like to think I would, though I might become paralyzed with fear in such a circumstance.
I definitely wouldn't sacrifice myself to save 1 stranger. Maybe several strangers, like someone else said, but I can't put a value to how many lives I would trade for mine. I would like to think I might be able to throw my life away to save that of a loved one, but if push came to shove, I can't honestly say that I would for sure. I suppose this makes me look like a selfish coward with no honor or something, but I think I'm far more useful to the people I love alive than dead, and there's no dishonor in running away if it means I can fight another day.
It would depend upon the preexisting situation. I have children - would they be protected and provided for it I died? If so then yes, I would die for another - but I need my children to be cared for. I would die for the children without a thought, but I do not feel I would be able to die for another and leave them alone.
In a hypothetical situation where I have no children, I would dive in to help the person and die in the process.
I have moderate emotional consideration for strangers because of Samaritan values imbued upon me by my parents, though not stemming from religion.
Therefore, in a situation where sacrificing my life would save a person, rather than leap to a decision to sacrifice my own life, i would assess the risk to myself versus the person and seek a way in which to save us both, even if given a binary decision.
Depends. I might do it for a child, or for someone with far more potential in life than I, but not for your regular average Joe. I wouldn't just run off like a coward, though. I'd apologize, and let him know that I wanted to save him, but I just couldn't. Hopefully he would understand.
