"Vaisampayana continued, 'Then on the occasion of an almsgiving, O king, Kunti fed on a certain night a large number of Brahmanas. There came also a number of ladies who while eating and drinking, enjoyed there as they pleased, and with Kunti's leave returned to their respective
homes.Desirous of obtaining food, there came, as though impelled by fate, to that feast, in course of her wanderings, a Nishada woman, the mother of five children, accompanied by all her sons. O
king, she, and her children, intoxicated with the wine they drank, became incapable.
Deprived of consciousness and more dead than alive, she with all her sons lay down in that mansion to sleep. Then when all the inmates of the house lay down to sleep, there began to blow a violent wind in the night. Bhima then set fire to the house just where Purochana was sleeping. Then the son of Pandu set fire to the door of that house of lac. Then he set fire to the mansion in several parts all around. Then when the sons of Pandu were satisfied that the house had caught fire in several parts those chastisers of foes with their mother, entered the subterranean passage without losing
any time.It does not say anything about pandavas murdered Nishada deliberately. Pandavas burnt house to purely kill Purochana which I admit.. Does not look like they were aware of other casualties.. It was their bad luck.
