As a second answer to your same post ...
I've revised what I think I would want to do in that situation. I still think it makes sense to head for the door, yelling "I'm calling 911!" However, once that call has been made (20 - 30 seconds outside), I'd do more than merely yell in the front door, "The cops are on the way!" I would come after Wint any way I could, coming in the front door (leaving it open) and tracking him down. I'd also grab anything I could use as a weapon or shield.
If I could somehow flush Wint out of the house, that would be the best outcome. But, at a minimum, I would be delaying Wint considerably, because he would have to turn his full attention to me instead of possibly trying to kill the women.
This doesn't save Philip: only Wint's decision to save his own skin can save Philip. But, I think it saves the women.
So, Philip still has 50/50 odds of surviving. I put the adult women at 90% now. And I'd put my own at 70%, because I'd be taking on Wint and making myself the next most likely to die. I figure I need only 3 or 4 minutes at most until Wint runs away, knowing that the cops are on the way.
