Revenge is a destructive violent response to anger, injury, or humiliation.Revenge is an intentional target with the intent of doing harm to individual.Desire for avenging on others satisfies self only.It increases Bad Karma and gets you caught in the cycle of birth and Death.
Revenge is an attempt to eliminate shame and increase dominance. Instead, it usually increases violence. Intention to take revenge is the general feeling that individual have to defend the honor of themselves and their family.
One feels pride of taking revenge may be a momentarily satisfaction.Revenge can not change the past but the present and the future. Revenge is a poisonous emotional negative thought.It is condemned in Spiritualism...Vedas & Upanishads.Even in Bhagavad Gita Krishna advises to fight for Dharma but he doesn't promote avenging!
Revenge is indeed a strong feeling in Mahabharat...Harvest of hate is bitter. Very bitter. All those who wanted revenge, got what they wanted in some measure. But, they had to pay a heavy price for their vengeance. Most lost their lives to exact the revenge or they so desperately craved someone they could not live without. So if anything, the epic tale teaches us that revenge is a poison not worth taking.

Krishna definitely is against hatred and revenge. It would have been easy for him to excite Arjuna by reminding how the Duryodhana brothers insulted Draupadi and it could have worked. No, Krishna did not want Arjuna to fight out of hatred, anger or for taking revenge. Krishna also is not interested in bringing Duryodhana to justice. Duryodhana has to die because he has been the instrument to deterioration of Dharma.Krishna wanted Arjuna to fight for Dharma without Attachment by giving up his ego and surrendering to him!
