The "right" answer...
...was to be an (almost) complete and utter amoral bastard. For example, if there's three people on the roof, and you will lose one person freeing them, free them and arm them. If a bud has been bitten and is going to turn, tie him up and trap him with TNT. Stuff like that.
When somebody asks you to trade your security for freedom, it isn't your freedom they're talking about.
