VyasaBharat states differently. Karna yearned to be a Kshatriya. He always wanted righteous war. Not manipulation.He may not come close to the Pandavas on Dharma, what with Krishna on their side, but he had a very high moral compass, which did slip up when his emotions overcame him. As for Suyodhana, he was misled and encouraged to abuse power from when he was born. Where was Gandhari when she could have told him otherwise? She came to the Dyut Sabha to plead with Panchali to not curse Hastinapura, but where was she when her sons were being fed with poisonous thoughts? It was bad parenting that led Suyodhana astray. The fantastic upbringing Kunti gave the Pandavas served as their way in life as well.
"Some time after, Duryodhana again mixed in the food of Bhima a poison that was fresh, virulent, and very deadly. But Yuyutsu (Dhritarashtra's son by a Vaisya wife), moved by his friendship for the Pandavas, informed them of this. Vrikodara, however, swallowed it without any hesitation, and digested it completely. And, though virulent the poison produced no effects on Bhima.
"When that terrible poison intended for the destruction of Bhima failed of its effect, Duryodhana. Karna and Sakuni, without giving up their wicked design had recourse to numerous other contrivances for accomplishing the death of the Pandavas. And though every one of these contrivances was fully known to the Pandavas, yet in accordance with the advice of Vidura they suppressed their indignation.

"Vaisampayana said, 'Thus worshipped by Bhishma, Drona, that first of men, endued with great energy, took up his quarters in the abode of the Kurus and continued to live there, receiving their adorations. After he had rested a while, Bhishma, taking with him his grandsons, the Kaurava princes, gave them unto him as pupils, making at the same time many valuable presents. And the mighty one (Bhishma) also joyfully gave unto the son of Bharadwaja a house that was tidy and neat and well-filled with paddy and every kind of wealth. And that first of archers, Drona, thereupon joyfully, accepted the Kauravas, viz., the sons of Pandu and Dhritarashtra, as his pupils. And having accepted them all as his pupils, one day Drona called them apart and making them touch his feet, said to them with a swelling heart, 'I have in my heart a particular purpose. Promise me truly, ye sinless ones, that when ye have become skilled in arms, ye will accomplish it.'
"Vaisampayana continued, 'Hearing these words, the Kuru princes remained silent. But Arjuna, O king, vowed to accomplish it whatever it was. Drona then cheerfully clasped Arjuna to his bosom and took the scent of his head repeatedly, shedding tears of joy all the while. Then Drona endued with great prowess taught the sons of Pandu (the use of) many weapons both celestial and human. And, O bull of the Bharata race, many other princes also flocked to that best of Brahmanas for instruction in arms. The Vrishnis and the Andhakas, and princes from various lands, and the (adopted) son of Radha of the Suta caste, (Karna), all became pupils of Drona. But of them all, the Suta child Karna, from jealousy, frequently defied Arjuna, and supported by Duryodhana, used to disregard the Pandavas. Arjuna, however, from devotion to the science of arms, always stayed by the side of his preceptor, and in skill, strength of arms, and perseverance, excelled all (his class-fellows). Indeed, although the instruction the preceptor gave, was the same in the case of all, yet in lightness and skill Arjuna became the foremost of all his fellow-pupils. And Drona was convinced that none of his pupils would (at any time) be able to be equal to that son of Indra.
