Mbh 10.5.4

"'Ashvatthama said, "Without doubt, it is even so, O maternal uncle, as thou sayest. The Pandavas, however, have before this broken the bridge of righteousness into a hundred fragments. In the very sight of all the kings, before thy eyes also, my sire, after he had laid down his weapons, was slain by Dhrishtadyumna. Karna also, that foremost of car-warriors, after the wheel of his car had sunk and he had been plunged into great distress, was slain by the wielder of Gandiva. Similarly, Shantanu's son Bhishma, after he had laid aside his weapons and become disarmed, was slain by Arjuna with Shikhandi placed in his van. So also, the mighty bowman Bhurishrava, while observant of the praya vow on the field of battle, was slain by Yuyudhana in total disregard of the cries of all the kings! Duryodhana too, having encountered Bhima in battle with the mace, hath been slain unrighteously by the former in the very sight of all the lords of earth. The king was all alone in the midst of a large number of mighty car-warriors standing around him. Under such circumstances was that tiger among men slain by Bhimasena. Those lamentations that I have heard, of the king lying prostrate on the earth with his thighs broken, from the messengers circulating the news, are cutting the very core of my heart. The unrighteous and sinful Pancalas, who have broken down the barrier of virtue, are even such. Why do you not censure them who have transgressed all considerations? Having slain the Pancalas, those slayers of my sire, in the night when they are buried in sleep, I care not if I am born a worm or a winged insect in my next life. That which I have resolved is hurrying me towards its accomplishment. Hurried as I am by it, how can I have sleep and happiness? That man is not yet born in the world, nor will be, who will succeed in baffling this resolution that I have formed for their destruction."'
