The ruthless Chakra-Vyuha was not known for killing with a fatal blow, instead it used to tear the enemy apart, flesh by flesh ; it allowed the enemy to scream in agony ; it calmly observed the enemy giving his everything to break free ; it watched in amusement when the enemy brought out every last bit of valor left, as a desperate attempt ; and at last, when there was nothing remained for him to continue fighting, then with just another gentle stroke, it used to stop the heart beat forever. No wonder, out of 18 Akshauhini Mahabharata warriors, only 7 dared to enter a Chakra-Vyuha, willingly.
