Scenario:
You're lost in a blizzard.
You'll die if you don't find shelter soon.
You find a tiny cabin.
You go inside the cabin only to find its empty but seems recently occupied.
Looking through the cabin you find a pistol and pick it up.
A rough and crazed looking individual bursts through the door and says "What are you doing in my cabin!?!" and rushes toward you in a grabbing gesture.
What do you do?
@Wetrix that's a good answer. If you'll indulge me...
*You hit him with the pistol*
He falls to the ground, moaning but conscious.
If you choose to leave..
Do you leave him with the weapon or take it with you?
If you choose to stay...
Do you try to reason with him essentially at gun point?
