War Mahabharat

One more fact, war never brings peace and happiness through war. 

It satisfies the revengeful mind, false ego for the satisfaction of ego and vanity only. 

Draupadi took revenge for her humiliation by Dusasana and Duryodhana. 

She used to provoke Pandavas 

The humiliation, injustice she had been suffering throughout her life for the revengeful war a rebellious mind for the winning back of their kingdom Hastinapur or equivalent possession of lost states Indraprastha too. 

Ultimately Bhima was successful in taking revenge on killing dushasana in cruelty and violence slaying his hands, tearing his heart in blood cleansing the hairs of Draupadi in that blood, 

These are obviously cruelty against one civilization.
