2-3 of my answers are marked either opinion based or the answers their don't justify fully.
Following the rules of site is at one side, but knowing the truth related to Hinduism is not a wrong.
Here are the questions I'm still expecting answers:
Did Karna think that it was adharma to not appoint Duryodhana as king of Hastinapura?
Why Krishna wanted to support Pandavas even when both Pandavas and Karuavas were wrong in dice game?
If everything were in books, I wouldn't need to ask them here.
Again, my motive is to understand the importance of Mahabharata war. It seems unfair to me Krishna supporting Pandavas. According to Balarma, both did adharma. And adharma is not small or big.
