Too bad that they had to kill the terrorists. That's what these maniacs probably preferred - if they can't escape, to go out like "heroic martyrs" who are celebrated by other maniacs. It would have been much more appropriate to give them a proper trial, let them rot in a cell, and hope that there is some humanity left in them that would have let them regret their insanity one day.
At least they can't harm anyone anymore.
