Why was Mahabharat necessary when Shri Krishna could have killed all the Kauravas and their allies with Sudarsan charkra?

After 13 years of exile , when Pandavas returned back to ask for Indraprastha they were denied to have it and when Krishna went to Hastinapur and asked Duryodhan to reconcile his decision then why didn't he kill all the Kauravas and their allies (except for karna because of his kavach and kundal) because this could have saved millions of people who died in the war ??
