I'm not putting you on the spot, but here's a better situation:
Guy commits arson on your whole building. Your mom and/or dad are in your apartment on the 17th floor. The likelihood of them escaping is almost nothing. In fact most of the people in your building are about to die. All your stuff is up there too of course.
Arsonist accidentally set himself on fire and is escaping. He can either die to fire, or you can let him escape and probably go unpunished and may commit more arson, who the fuck knows?
You'd let him escape?
