executing them now is sure to get you killed if the regime changes in future.... that's just plain stupid
similar to nazi war crimes as long as they could plead to following orders/law under the threat of death they can get away pretty easy
but "executing" the sentence now is not just law/orders thats revenge or fear of revenge and if they cant claim the following orders/law defence they will get a capital punishment in future
not to mention that they loose major blackmail material on ebony whom they "fear"
but i guess those guards aren't very bright to begin with
still i will never understand people signing their own deathwarants without any need to do so
