U have only read and interpreted what u want ! Yes, kill your blood relative, in a fair war, if he is on the path of Adharma /Wrong ... Fight war only when no alternative is available to secure your rights ... Follow tthe path of truth and Karma - sow as u reap ! OK ? Did the pandavas take sex slaves like Muhammed did with juwahariyaan after killing her husband ?
Also know, Pandavas were ready to settle for just 5 villages, Duryodhana didnt even agree to that, he trickde them into a game, sent them to forests for 13 years ! Wouldnt the pandavas fight back ?
