There are many reasons for Lord  Krishna coming to this worldly plane , and in reality, only His devotees know of them , both esoteric  reasons and reasons of  establishing compliance and governance within human societies . He sets standards , by His examples that great men can pursue, and this  is  achieved by  His impeccable activities . Lord Rama particular was concerned with establishing good governance,  and He demonstrates,  that a leader must listen to all the people , and be prepared to make a sacrifice , even if it might be hard to bear .

In the first Canto of the Srimad Bhagavatam, we hear of Yudhisthira appearing before Bhismadeva , who was lying on a bed of arrows , preparing for death . Yudhishira lamented  that the battle at Kuruksetra was just to establish him on the throne , and so many had to die for that end  to be achieved.

But Bhismadeva informed him of several things , that eternal activities within material nature  are all under the control of time,  and ultimately Krishna says” time I am the destroyer of all things . ” Ultimately Krishna wanted , on the battlefield of Kuruksetra,  to destroy political systems that are not based on either proper Vedic standards ,  or  that are based on   personal ambitions  unfit persons  that   were exploiting politics , for their own end , and in doing causing suffering , and disrupting  the natural direction and progression in everyone’s lives , Krishna favours  harmonious respectful societies with Saintly leaders

The founder of ISKCON AC Bhaktivedanta Swami explains in his purports to the Bhismadeva incident ,  when there are  good leaders who are sensitive to all beings , and understand justice and the  regulative principles of freedom then people do not suffer  unnecessarily . Bad leaders create suffering.

One can tell the current quality of leadership,  look at turmoil in the world .

Prabhupada was also fond of quoting  a Bengali poet ,

“One who does wrong or suffers wrong is wrong. “

Thus the mature Vedic student has to realise,  that an convenient answer of ..”.it’s just your Karma..” .has to be balanced out , by seeing to it that anyone in position of power is acting absolutely correctly and impeccably,  if he or she is unqualified , unnecessary suffering ensues , and those subjected to suffering by poor and unqualified leaders , should strongly protest and seek proper justice , but only with the help of an authorised judiciary.
