The Fire and The Girl: You Choose Your Storyline

Part 1

You wake up in your apartment building and you smell smoke. You take your backpack and get outside of your apartment into the hall, and see fire all around you. No one else is in their apartment but you. You are on the tenth floor and cannot jump out a window. There are only two doors you can enter.

Door A has a window that is blocked on the by smoke and flames. Door B has no windows and you have no idea what could be on the other side. Which door do you go through?

Option (Door) A: You go through Door A and you are immediately engulfed in flames. You can no longer find the way back out. You die horribly and your body is completely burnt to a crisp.

Option (Door) B: You go through Door B and thankfully the fire hasn't reached here. You continue to find your way out...

You see that there could be some useful stuff to collect. You collect a knife, pepper spray, some granola bars, and some water bottles. You head to the next floor, you are now on the ninth floor. Suddenly you hear a small voice saying 'Help! Help! Please help!' You go to investigate and see a little girl on the floor holding a gun. She looks about seven years old. Next to her is a woman with a bullet hole in her head that looks like it is her mother. 

Should you [A] ask her her name and if she is ok or [B] kill her with your knife.

Option A: You ask her her name and she answers saying her name is Alex. When you ask whats wrong she says she accidentally shot her mother. She says she is scared and wants to get out of the building. You continue and bring her along...

Option B: As soon as you step near her, the little girl holds up her gun. She aims it at your head. "I will shoot," she says. She shoots you in the head killing you and scattering your brains all over the room.
