These pacifists are so trapped by the illogic of their irrationality, I would suggest next time rescue squads locate hostages, turn the video cameras on, and clearly ask each hostage if he/she wishes to be rescued. For each "no", the rescue squad will leave behind a note for the terrorists, explaining that CPT will be along shortly to "collect" them.
This way, only hostages with a clear desire to live will be rescued.
