Pandavas are willing to change; they want to outgrow the beast within them. The process of change is difficult—the Pandavas have to suffer exile, kill loved ones and lose their children, in the process of gaining wisdom. The Kauravas cling to their kingdom like dogs clinging to a bone. They refuse to change. Hence, they die without learning anything. Krishna is the teacher. But the onus of learning rests with the students.
