Mbh 5.92.1a

Vaisampayana said, “After Kesava had dined and been refreshed, Vidura said unto him during the night, ‘O Kesava, this advent of thine hath not been a well judged one, for, O Janardana, Dhritarashtra’s son transgresseth the rules of both profit and religion, is wicked and wrathful, insulteth others, though himself desirous of honours, and disobeyeth the commands of the aged. He is, O Madhava, a transgressor of the scriptures, ignorant, and of wicked soul, already overtaken by fate, untractable, and disposed to do evil to those that seek his good. His soul is possessed by desire and lust. He foolishly regardeth himself as very wise. He is the enemy of all his true friends. Ever-suspicious, without any control over his soul, and ungrateful, he hath abandoned all virtue and is in love with sin. He is foolish, with understanding uncultivated, a slave of his senses, ever obedient to the impulses of lust and avarice, and irresolute in every act that should be done. He is endued with these and many other vices. Although thou wilt point out to him what is for his good, he will yet disregard it all, moved by pride and anger. He hath great faith in Bhishma, and Drona, and Kripa, and Karna, and Drona’s son, and Jayadratha, and, therefore, he never setteth his heart on peace, O Janardana. Dhritarashtra’s sons, with Karna, firmly believe that the Pandavas are incapable of even looking at Bhishma, Drona, and other heroes, not to speak of fighting against them. The foolish Duryodhana of limited sight, having assembled a huge army regardeth, O slayer of Madhu, that his purposes are already achieved. The foolish son of Dhritarashtra hath arrived at the conclusion that Karna, single-handed, is competent to vanquish his foes. He will, therefore, never make peace. Thou, O Kesava, desirest to establish peace and brotherly feelings between the two parties.
