Shakuni and Karna looked at Gandhari not knowing if they would be proud of her that even being in the court her thinking is this simple or sad for her as she still has not learned from the events that happened to her.
One alway learns from their mistake and she did but her soft nature no matter how hard she tried to suppress it always comes out making her think of giving forgiveness to those who should not even deserve her audience.
She is right they are many people there in kingdom for to protect Duryodhana if some outside force wanted to harm him, He does not doubt it even if not for the protection of Duryodhana this hypocritical royals of Hastinapur will fight to protect him for to keep their honour and authority.
But what will happen if the threat to him is from inside their own house? He already knows how many hungry people are staring at them like a group of hyenas waiting for them to make a mistake, So they can eat them whole without leaving even bones.
