Who is the righteous king of Hastinapur is a debatable topic. The only reason Pandu got the throne is because of blindness of Dhritrashtra. And after death of Pandu the throne is taken by Dhritrashtra.
Wrong deeds of Kaurvas :
~ Trying to kill Bhima
~ Laxagraha Episode
~ Draupdi Chirharan (Bhishma and [[Drona oppose this move recalling that a woman cannot be put at stake even if it is their own wife. However, Yudhishthira ignores their call and puts her at stake much to the ire of Bhishma, who in his frustration breaks his chair. )
~ Killing of Abhimanyu
Wrong deeds of Pandvas :
~ Bhima teasing all Kaurvas boys (Which is the reason Suyodhana started hating pandvas)
~ Sacrificing others for own benefits in Laxagraha
~ Draupdi insulting Duryodhana, Dhritrastra and Karna
~ Extermination of entire tribes to build Indraprashtha. This clearly shows greed of Pandvas towards kingdom.
~ Killing of Bhisma
~ Killing of Drona
~ Killing of Karna
~ Killing of Bhagdatta
~ Killing of Bhrurishrva
So deciding who was right or wrong is quite a tough call.
