Why Does Khan Deserve a Rematch..?

Khan refused to give Barrera a and Mc Clownskey a rematch after getting both fights stopped by illegally comin in with his head and cutting them open. Khan refused to give prescott a rematch who knocked him spark out.. Khan refused to give Maidana a rematch who almost knocked him out... Petereson was the mandatory challenger for the IBF title .... So there is no rematch clause as would be the case for a voluntary defence .... So can some please explain why the hell khan even deserves a rematch. He should be told go and prove urself in a rematch against one of the above and ill consider giving u a rematch
