Self-Preservation Or Self-Sacrifice: Which Would You Choose ?

You and a stranger are walking along a steep cliff when you both slip and you find your self holding on for dear life to a small branch while the stranger is holding on to your legs. Falling means certain death.

You do not have the strength to pull both of you up to safety but you could pull yourself up if you kicked the stranger loose and the stranger does not have the strength to climb over you. No one will come to your rescue and your hands are slipping.

What do you do ?

Now the situation is reversed and it is you dangling from the legs of a stranger over that cliff what do you do ?

If it was not a stranger but someone you loved deeply like your child or mother or lover would you behave differently in those same situations ?
