Why did the Pandavas delay killing of Shakuni?
Specifically, I think if Shakuni was killed in the first day itself ( which I think was easy), the Mahabharata war would have greatly reduced in intensity and I think would have finished earlier. This is because, he was the main antagonist who ignited Duryodhana more and more. If we remove the fuel for Duryodhana, then chances are that he would have surrendered to Pandavas seeing the immense stalemate like situation between Bhishma and Arjuna.
Any light on these facts based on scriptural anecdotes? Thanks beforehand.
