What's "wrong" about it? Was it wrong to kill Ben Kenobi in Star Wars? Was it wrong to kill Boromir in LotR? Was it wrong to kill any of the innumerable characters in Lost who died? These people are in extreme circumstances, and I think there's a valid argument that what's "wrong" is painting the situation as though everyone "important" is going to come through it unharmed. Though God help you if your name isn't in the main credits.
